| Summary: | 碩士 === 中華科技大學 === 飛機系統工程研究所 === 104 === The thesis aims to take yield surface distortion into account in order to investigate cyclic elastic-plastic behavior. Finite-element commercial codes provide elastic-plastic analysis for multi-purposes. However, they do not take into account yield surface distortion. Therefore, we enhance the capability of ABAQUS in the simulation of yield surface distortion by editing the user subroutine. The advanced constitutive model considering the distortional hardening available in the literature is adopted. Case studies are performed by ABAQUS and compared with those experimental and numerical results of SS304/CS1026 published in the literature, in order to test and verify the correctness of user subroutine.
