Abstract

To solve the defect of common finite element analysis which cannot imitate the micro-structure and mechanical properties of materials, a new kind of FEA model is founded to simulate the metallic micro-structure based on the dispersed mechanical characters. Some research is performed by this model on the low-cycle fatigue process where top process in the cycle is slightly under the yield stress. Firstly a theory model towards the process of elastic and plastic deformation coupled with damage accumulation is founded. Secondly some simulation is performed by the new FEA model. Finally the simulation is verified by tensile and compressing experiment. The experimental results show that the new FEA model can simulate the deformation of metallic materials in micro-level accurately.
