Abstract: There is a growing demand in the dental implant sector which aims to recreate the exact function and appearance of natural teeth, including strength, textures, and seamless blending with nearby teeth. Therefore, choosing the best crown material is a vital and challenging decision. To address this challenge, current study employs a comprehensive approach using Finite Element Analysis (FEA) on a 3-D CAD model. The stress analysis was carried out on three different crown materials - commercially pure Titanium (cp Ti), Zirconia (ZR), and Lithium Disilicate (LD) and compared their performance with that of human tooth material. The computational analysis results reveal that the pure Titanium (cp Ti) crown has shown the least deformation while the LD crown has showed the highest deformation under same loading conditions. When maximum stress is compared, Titanium showed the highest value, followed by Zirconia, whereas Lithium Disilicate (LD) demonstrated stress and deformation levels comparable to those of natural teeth.

Abstract: The article is devoted research of process equipment in the simulation of the stress-strain state of load-bearing elements in the environment of ANSYS. The obtained results are consistent with the data of preliminary calculations and confirm the performance of device. The device for connecting the ends of a conveyor fabric-rubber belt by a vulcanization method is a set of ten segments. At the stage of preliminary calculation stress-strain properties of supporting profiles vulcanizing press were determined by using SCAD software. Point load of hydraulic cylinders is transmitted on profiles in accordance with terms of reference. Strength calculation supporting profile in ANSYS software was carried out using Finite Element Method. The segment of the device under consideration is symmetrical with respect to two planes. Therefore, it was decided to simplify the calculation model using the capabilities of the ANSYS software, namely using the "Symmetry" modifier. This simplification reduces the requirements for computing power of the computer, which, in turn, allows to build a better mesh. Mesh is constructed mainly from eight-node volumetric elements of regular shape. Analysis of the supporting profile in ANSYS software confirmed the results of preliminary settlements. There are stresses in the dangerous sections of the upper profile exceeding the yield point. Despite this, during unloading, residual deformations in the profile are absent, since for the most part of the profile length in the sections there is no limiting state, that is, the stresses do not reach the yield point.

Abstract: The concept of parallel manipulator is becoming more popular in modern manufacturing processes due to its various inherent advantages like rigidity, less inertia and accuracy. This project focuses on modeling, simulation and dynamic analysis of inverted tripod parallel manipulator which has three degree of freedom (1 transverse in z axis and rotation motion in x and y axis). The Stewart Gough parallel manipulator consists of moving platform connected to fixed platform with six links (6 Degree of Freedom).This inverted tripod parallel manipulator consists of movable platform connected to the fixed platform with only three links so it has better rigidity compared to Stewart Gough platform. The Stewart Gough parallel manipulator is considered to be highly stable because moving platform size is smaller than the fixed platform. Inverted type parallel manipulator consists of moving platform bigger than the fixed platform. So to improve the stiffness and precision ball screw is used for the support of links. The design of parallel manipulator is done considering rigidity, strength and efficiency of the system. The modeling of the tripod manipulator is done using PRO-E software. Kinematic analysis has been carried out and the stiffness analysis will be done by using ANSYS and ADAMS software.

Abstract: It studied the early stability model of tunnels and establish the computer information system of early stability by using general software of ANSYS and Matlab in the paper. Firstly,the stress is displayed successfully through the model of stress intensity checking and algorithm. Then,it analyzed the influence of stress on surrounding rock in the arching process by using ANSYS software to calculate stress distribution in surrounding rock.Finally,it obtained the visualization display by using Matlab. Due to the limited conditions of computer, the numerical modeling process can not simulate the real situation of surrounding rock,we can only use approximate models to replace the whole rock system.

Abstract: The butterfly valve system is an important part of the steel heating furnace temperature control. In high temperature, the coupling effect of temperature field and stress deformation of the butterfly valve is stronger. We did not consider it in the numerical simulation research in the past, and studied the overall characteristics of butterfly valve only by 2D numerical simulation, resulting in the decrease of the numerical simulation accuracy. This paper uses the way of the FLUENT software and ANSYS software joint control, and has established the mathematical model of fluid and solid coupling effect, and has implemented the coupling effect of the temperature field and stress field of the butterfly valve system by means of three dimensional numerical simulation, then we have got the temperature distribution and stress distribution of the butterfly valve system, which provides technical reference for mechanical system design of butterfly valve.

Abstract: In this paper, we use foam injection coagulation method to fabricate SiC/mullite porous ceramic with porosity 38-80%. In order to study the performance of the ceramic, we use the principle of cavity to establish the fourteen surfaces model of the SiC/ mullite porous ceramics, and use the ANSYS finite element simulation software to simulate the performance of ceramic, and do simulation on the mechanical properties of the ceramics. In order to study the influence of different wall thickness and curvature on the properties of ceramics, we calculate the structure stress distribution of fourteen surfaces when wall thickness is 0.4 and 0.5mm. When the wall thickness is 0.2mm, we study the structure stress distribution with radius 0.1mm and 0.2mm. So we obtain the influence of wall thickness and curvature radius on the properties of porous ceramics. It provides valuable reference data for the study on porous ceramics.

Abstract: This paper presents a three-dimensional entity model to analyze the creep effection of PC continuous rigid frame bridge and simulate the impact of longitudinal cracks at the bottom of mian span on the deflection briefly with ANSYS software. The result shows that creep amplifies the deflection of bridge and makes the position of maximum deflection move to the center of mian span. And the longitudinal cracks of mian span don’t make great contribution to the deflection of PC continuous rigid frame bridge directly. Actually, the cracks change the stress state of the bridge’s section, which results in the risk of web cracking and further the stiffness degradation of structure. The stiffness degradation increases the defection of bridge to a great degree finally.

Abstract: On the basis of Umansky box-girder torsion theory, the software of ANSYS is applied to simulate related engineering model. In considering a variety of live load conditions, the lateral stability of multi-span single-pier variable cross-section box-girder under torsion eccentric load is analyzed. Analysis results reveal that under different working conditions, the factors affecting the transverse stability of the bridge and the proportion of the value on each, such as gravity, the span ratio and the distance between support are different; When the overload ratio is 2 times larger, the bridge stability safety coefficient decreases along the curve and changes rapidly. In the future design of this kind of bridge, the overall lateral stability should be paid much more attention. Some methods and suggestions about how to prevent the emergence of security and stability problems are put forward in the end.

In order to study the physical properties of environmental rubber concrete, we use methods of experiment and numerical simulation to test mechanical parameters and effect of thermal insulation of concrete. Through the experiment we obtain the relation between ultimate bearing capacity and temperature. We use the software of ANSYS to secondary development on c numerical calculation, and establish a mathematical model of road drainage tube. Through the numerical simulation we get the temperature distribution and the radial strain nephogram of environmental rubber concrete. It provides a new method to study new materials in road engineering.
