陶瓷颗粒增强铝基复合材料残余应力的多尺度模拟
Multiscale simulation of residual stress in aluminum matrix composites reinforced with ceramic particles
摘要
Abstract
This study was to investigate the effective elastic response characteristics and residual stress evolution mechanism of ceramic particle-reinforced metal matrix composites,and an innovative multiscale elastic response model incorporating the effective representative volume elements was constructed through a multi-scale modeling strategy to achieve a cross-scale correlation from micromechanical elastic response to the macroscopic mechanical behavior.The effective elastic properties and residual stresses of composites with varying A356 contents were theoreti-cally predicted by taking Al2O3/A356 composites as an example.The results are shown that the effective elastic constants of composites gradually decrease with the increasement of A356 contents,exhibiting a distinct softening effect.Under mechanical loading to the composites,there is compressive stresses in the Al2O3 metal phase,and the compressive residual stress in the composites varies with the A356 in a nonmonotonic pattern of first increasing and then decreasing.These predicted values of the effective elastic properties and residual stresses show a good agreement with experimental measurements,validating the accuracy of the proposed model,which provides a theoretical founda-tion for the forward design and performance optimization of composites.关键词
