Abstract

A model found by finite element method was developed in COMSOL Multiphysics to describe the evolution of residual stress after quenching of cylindrical samples of aluminium alloys AA2014 and AA5083. The treatment consisted of annealing followed by quenching in fresh water. The thermal and mechanical properties of both alloys at the annealing and room temperatures were taken into account. A different sample size was considered for each alloy. The simulations show that the residual stress strongly depends on the yield stress and sample size. The results obtained by the finite element method were compared with the experimental residual stress profiles calculated from neutron and X-ray diffraction data.

由衍射实验和有限元法模拟得到的淬火处理后残余应力分布

摘要

在 COMSOL Multiphysics 中开发了一个通过有限元方法建立的模型，用于描述铝合金 AA2014 和 AA5083 圆柱形样品淬火后残余应力的演变。处理包括退火，然后在淡水中淬火。考虑了两种合金在退火和室温下的热性能和机械性能。每种合金都考虑了不同的样本量。模拟表明残余应力强烈依赖于屈服应力和样品尺寸。将有限元方法获得的结果与根据中子和 X 射线衍射数据计算的实验残余应力分布进行比较。
