Moreover, from the point of view of cost, many
factors such as the feed bridge, process quality and die scale should be considered.
Drawing is the crucial process and it will affect other processes and die structure.
Forming performance at this area depends on the lubrication, material properties and some other processing conditions.
For the specific drawbead, factors affecting the resistance force mainly are the radius of the round corner, height, width, gap and some other parameters.

Abstract:Finite element method(FEM) have been widely used in modern mechanical design,mesh generation is an important part of the finite element analysis,this article discussed the process of mesh generation through two practical cases and put forward some issues we should pay more attention to.
The finite element analysis software mainly includes three core components:pre- processing module,analysis module and the post-processing module.Pre-processing part which accounts for about 45%~50% of the entire workload,post processing is about 55%~60% ,Only about 5% of the computing section[2].Pre-processing is the basis for follow-up work,the quality of pre-processing directly affects the accuracy of the model results.The core content of pre-processing is mesh generation,it will consume most of time of the pre- processing.The mesh generation is an important content in the finite element model,it has large workload and many factors should be Considered, therefore it is necessary to do some technology research to summarize the method of mesh generation.
Secondly, in order to ensure the correct transmission of force and moment,Displacement coordination is an important issue we must consider.A node of element must be adjacent node element,but not the interior point or boundary point,the node of the adjacent cells should have the same freedom properties[3].
At last good transition between the units is also a issue what we must conside,Unsmooth transition may reduce the accuracy of the results or even can not be calculated.Element shape also affects the calculation results,Regular polygon and polyhedron is the best choice.

Introduction
Fabrication of high-temperature superconductor ceramics with optimum electrical properties and stable mechanical behavior is essential for application in power engineering system such as fault current limiter and energy storage.
Nevertheless the Bi-2212 superconductor, like other high-temperature superconductors has poor mechanical properties such as low stiffness, strength and toughness.
Low strength and low irreversible strain are among the factors that hindered the application of superconductor in power industry.
Furthermore, MgO fibers have been used to reinforce composite materials and they are able to improve the mechanical properties of the compounds [3].
Optimum superconductivity properties with significant enhancement in strength of the Bi-2212 superconductor compound are exhibited in sample with 5% nanosize MgO addition where lower grains orientation of Bi-2212 phase is observed.

This was interpreted as the modification of the
residual stress field due to the mechanical indentation.
The way the defects are generated can have strong influence on the results, especially for shot peened samples, because it is a factor that can modify the residual stresses field introduced by this treatment.
This method slightly modifies the pre-existent residual stress field and the local mechanical properties of the material compared with mechanical work.
The smaller microholes where done with an indentation device, surely affecting the residual stresses field introduced by nitriding and shot peening treatment, while the larger defects are obtained by electroerosion much less invasive with respect of residual stresses.
The defect obtained by electro-erosion is more suitable for determining fatigue properties of nitrided and shot peened material.

Vegetable fibers properties are influenced by many factors including plant type, growth condition, and method used to extract the fiber [7].
This could produce composite with weak mechanical and physical properties [8].
Some previous studies have shown that hybridization improves some mechanical properties of polymer composites [24, 25].

In general, ferrites have a polycrystalline structure and are made up of iron oxide as their main constituent with good mechanical properties and black or grey color in appearance.
Manipulation of different processing factors, such as composition, particle size, sintering temperature, heating rate, milling duration, etc. can lead to substantial variations in grain size and determine the performance of the material [7].

The goal in this work is to build a multivariate linear model to predict tensile strength since is one of the most significant mechanical properties of carbon-black reinforced rubber blends.
This model is based in the relationship between the final mechanical properties and the material composition, with the advantage of using this model to improve the design of the composition of the blend.
Introduction Commercial rubbers are a complex mixture of very different components, where each of these components takes to affect in the final physicochemical properties of the rubber blend.
Several techniques like data pre-processing, outlier detection, analysis of variance, analysis of covariance, analysis of correlation, multivariate data visualization, and Principal Components Analysis (PCA) are applied to study the influence of each composition variable in the output mechanical properties and to finally select the most significant variables to perform the most accurate models.
However following the explained methodology two important factors for model validation are improved.

Kim et al.[6] investigated the effects of microstructure changes on the mechanical property of bulk bone and they found that the microstructure of cancellous bone played a pivotal role in the material properties of bone.
To further depict the connection between the microstructure and macro-properties, the correlation coefficient was calculated to analyze the architectural parameters and the material properties using regression method[7].
The architectural parameters are affected by many factors and a series of studies have tried to calculate the morphological indices of trabecular bone.
In addition, different shape of volumes of interests may be a factor that affects the parameters due to the anisotropic property of cancellous bone.
