纯铁相变和层裂损伤的数值模拟
Numerical Simulation of Phase Transition and Spall of Iron
摘要
Abstract
Based on the Hayes multi-phase equation of state,non-equilibrium phase transition rate and damage evolution rate equation,and the eonstitutive relation of materials,the numerical simulation method considering the phase transition and damage was proposed and then used to analyze the interaction between phase transition and spall of iron in the symmetric impact experiment of iron.The results show that it is only when the phase transition of pure iron occurs that spall emerges.In addition,the free surface velocities and the spall positions of the sample are in agreement with the experimental results.关键词
