摘要
基于变形梯度乘法分解 ,推导了延性单晶材料的弹性变形梯度演化方程 ,利用晶体弹粘塑性本构关系的和Taylor多晶假设 ,以面心立方晶体铝。
Based on a multiplicative decomposition of the deformation gradient, an evolution equation of the crystal elastic deformation gradient for ductile single crystals is obtained. The constitutive equation for an elasto-viscoplastic crystal is presented for modeling the texture evolution and stress-strain response of polycrystalline materials using Taylor hypothesis. The effect of hardening model on the evolution of polycrystalline materials Al and Cu is analyzed.
