Numerical simulation for manufacturing crawler board by multi-axial active pressing;

In view of the construction feature of abnor mal-axes,a kind of new multi-direction load press forming technology was proposed.

The present paper simulates the copper alloy Three Contacts multi-direction load way using finite element analysis software MSC-Superform2005 the forming process.

Using the finite element analysis software MSC-Superform,the forming processes of three-way pipe under different multi-direction loading way were simulated.

Coupled thermal-mechanical FEM analysis on multi-way loading forming process of triple valve body

Thus,the multi-way loading process provides an efficient way for precision plastic forming of the key and large-scale components of material difficult to deform.

This paper describes the theoretical analysis of the stratigraphic rock strength change with the increasing loading rate at dynamic loading by utilizing the basic theory of the rock mechanics and fracture mechanics.

Depending on relationship between critical stress and temperature of phase transformation,the paper firstly analyzed the process of phase transformation under dynamic loading,then developed the theoretical model with Brinson static constitutive equation,conservation of energy and heat transfer theory,performed some simulations under Matlab 6.

Single-pass pendulum scratching test,characterized by dynamic loading,is a new method of measuring friction and wear of materials.
