However, there are many factors affecting the final deformation of the processed steel plate, which are difficult to predict.
Material Properties and Boundary Conditions Material properties, including material density, Young’s Modulus, and Poisson ratio etc, are important in the estimation of plate deformation.
However, for the given carbon-steel plate, the influence of material properties can be ignored in the research.
The steel plate has a length of 1000 mm and the material properties of carbon-steel.

Most of these papers are focused on the effect of the welding parameters (tool rotation and traverse speeds) on the microstructure and mechanical properties of the welds or on the selection of adequate tool materials for welding copper alloys.
Though, the factors influencing the voids formation determined in present research for welding of copper alloys show quite similar effect to those observed previously for aluminium alloys.
Probably the degree of recrystallization in the nugget, this means the proportion of grains deformed (high dislocation density), substructured (low angle boundaries inside the grains) and recrystallized, affects the mechanical properties of the welds.

The main aim of the solution is to find a variable and to create a parametric mathematical model to calculate the appropriate grinding wheel shape according to the input factors which affect this issue – the hobbing worm and the grinding wheel parameters.
Theoretically such a negative effect of undercut should not occur because of the straight line properties of both input geometries.
Each of modules work based on the analytic geometric tasks, which are differentiated by input parameters and properties of the ground tool.
Each method involves the geometric properties analysis and the input parameters analysis and based on these informations the solutions are designed.
These data are the main factors influencing the curve shape.

Powder forming process can produce parts with homogeneous and satisfactory mechanical properties.
PM processes can develop new and functional parts with homogeneous composition and satisfactory mechanical properties.
The yield stress correspondent to an instantaneous deformation state is called flow stress, which is a function affected by deformation rate, temperature, deformation degree and some other factors, and it is related to properties of the matrix material.
In powder forming, due to the varying powder density during the deformation, flow stress is also affected by the density.
It can be seen from Fig. 3 that except in Kuhn’s researches, become softer with n grows; which n value can bring the more accurate results depends on the material properties.

The factors affecting gear transmission error include manufacturing error of gear, fit clearance of gear and shaft, fit clearance of shaft and bearing, and radial run-out tolerance of shaft neck which the gear is installed and so on.
After importing the final three-dimensional model into Ansys Workbench, defining the material properties, selecting the element type, and meshing, the finite element model is built as shown in Fig.8.
It is mainly affected by internal bearings of the fifth gear in A-axis transmission chain.
Improving the rigidity of the internal bearings can effectively enhance the local property.

Ge-chalcogenide glasses – properties and application as optical material Tamara Petkova1a, Vania Ilcheva1, P.Ilchev2аnd P.Petkov3 1Institute of Electrochemistry and Energy Systems, BAS, Sofia 1113, Bulgaria 2SENSATA Electronic group, Boutevgrad, Bulgaria 3University of Chemical Technology and Metallurgy, Sofia 1756, Bulgaria a e-mail: tpetkova@bas.bg Keywords: glasses, chalcogenide, properties, structure Abstract.The great interest toward chalcogenide materials is due to the simple technology of preparation in bulk forms and thin films; good thermal and mechanical properties; transparency and photo-sensibility in the IR spectral range.
They have a large range of transparency and good mechanical properties such as hardness, adhesion, low internal stress and water resistance.
The properties of chalcogenide semiconducting glasses are strongly dependent on their compositions.
Thus, the addition of third element in the binary system GeChal is expected to affect properties.
The glass transition temperature is considered to be proportional to the mean bond energy , which depends on factors like mean coordination number, degree of cross linking, bond energy and the nature of bonds.

It is insufficient to study some key factors such as the direct relationships between plasma jet characteristic, particle property and forming quality.
The particle properties of Al2O3 powder ranging of 10- 20µm measured at a spray distance of 120mm are shown in table 1.
Therefore, it indicates that H2 and Ar are the most influential factors for the particle temperature and velocity respectively.
Among the parameters given in the experiments, Ar flow rate is the main factor influencing on the particle velocity, while H2 flow rate is the main factor affecting the particle temperature.

The presence and the mechanical properties of the infills affected the distribution of damage throughout the structure.
Several researchers suggest different reduction factors to describe the decrease of stiffness, depending on the dimensions and the position of the openings.
In this study different stiffness reduction factors for different opening percentages were considered, according to Asteris [2].
The influence of the mechanical properties of the infill walls was less marked in presence of openings.
The presence and the mechanical properties of the infills affected the distribution of damage throughout the structure.

In the subsequent sections, the factors affecting water ingress in unstabilised earthen material and its disintegration are summarised and hence used in understanding the response of water ingress in biologically stabilised earthen material.
While these properties are inter-related, the factors affecting are not necessarily the same.
The various factors affecting the microstructural fabric and hydraulic conductivity are illustrated and summarised in Fig.1.

The mechanical properties of the nanocomposite with clay content up to 3.0% were improved.
The mechanical properties were determined using universal testing machine (UTM).
Mechanical Properties.
Another important factor to consider in the mechanical properties of the nanocomposite membrane was the Young’s modulus, which is the ratio of stress and strain.
Aside from the process, the membranes were all attached with the membrane support when DSC was performed, thus, affecting the DSC results for the sample membrane.
