An IGMG (Improved Grid Mesh Generation) is proposed in this paper. The algorithm combines the advantages of grid algorithm and traditional triangulation Delaunay algorithm, it generates quadrilateral/triangle mixed elements that ensured the overall and local performance. The result meshes meet the quality requirements of finite element mesh for automotive panel stamping forming simulation software. Practice has proved that the IGMG to be robust, efficient, generating meshes with high quality and easy to be implemented in practical applications. The algorithm has been successfully integrated into the commercialized stamping simulation software-KMAS.

Zone heating is frequently used in the free blowing of PMMA material to ensure the last forming figure. The temperature gradient distribution on the blank plays a key role on the quality of the last production in the temperature control free blowing forming procedure. In this article, the thermoforming of the aeronautic transparent component in PMMA material is simulated at the different temperature distribution with the static explicit finite element program. We use the BT shell element model and the constitutive equations fitted from the data of simple tension experiments to calculate. We find the best temperature gradient distribution along the vertical and horizon (Y and Z) direction.

In this paper,the proposed is a quasi-flow constitutive model with strain-rate sen- sitivity for elastic plastic large *** model is based on the Quasi-flow Corner theory, and is suitable for the sheet metal forming process simulation with a variable punch machine velocity. Uniaxial tensile tests and deep-drawing tests of a circular blank with square punch are carried out and numerically *** consistency between the experimental and the numerically simulated results shows the validity of the present new constitutive model.
The objective of this study is to develop a non-steady & non-linear tire model for vehicle dynamicsimulation and control for extreme lateral slip condition. This model is provided in a semi-analytical form based ...
