Element Method

A moving grid nonlinear finite element method was used in this study to simulate crack propagation. The relevant elements were split along the direction of principal stress within the element and thus automatic optimization processing of local mesh was realized. We discussed the moving grid nonlinear finite element algorithm was proposed, compiled the corresponding script files based on the dedicated finite element language of Finite Element Program Generator (FEPG), and generate finite element source code programs according to the script files. Analyses show that the proposed moving grid finite element method is effective and feasible in crack propagation simulation.

Element Method

The finite element program developed in previous work [1] for calculating the temperature distributions in the chip and tool in metal machining has been extended in its range of application. Specifically, the program no longer needs a flow field as input and it can accommodate a wide range of shear angle and contact lengths. An important feature of this paper is that temperature fields from the finite element method have been compared with temperatures obtained with a previously described metallographic method [7]. This is the first time these two techniques have been used for the same machining conditions and the comparisons are very good.

Modulus Method

The collapse settlement of loess foundation is one of issues in engineering which need to be solved. Firstly, a finite element program was developed and the computational function of collapse deformation was implemented based on chord modulus method. Then, the comparison of the measured collapse settlement in a loading plate test and the computational collapse settlement based on the finite element were analyzed. The computational results show that the nonlinear finite element method based on the chord modulus should be recommended to evaluate the collapse deformation, owing to its potential application that it may consider the collapse deformation field of the whole collapsible loess foundation.
