DZ22合金的各向异性蠕变损伤本构模型的建立及数值分析
Anisotropic Creep Constitutive Model of DZ22 Alloy and Numerical Analysis
摘要
Abstract
By means of an advanced tensorial damage method,a anisotropic constitutive model for the first and second creep process of DZ22 directional solidification superalloy was established according to Hill's anisotropic theory and Norton power law,using ANSYS software programming,and was compared with Kachanov-Rabomov (K-R) isotropic constitutive and uniaxial static creep test.And the parameterized creep behavior of DZ22 superalloy was also researched based on material orientation.The results show that the model of the creep strain is accurate.关键词
