matlab编写的三维各向异性有限差分正演程序(3D anisotropic finite difference forward modeling written in MATLAB)

In this paper, an anisotropic formulation of the Gurson-Tvergaard-Needleman (GTN) damage model is used for simulating the deep-drawing of a rectangular box made from an AA6016-T4 metallic sheet. The model is implemented as a VUMAT routine in the ABAQ

采用离散再合成的随机流动生成(DSRFG)方法合成了满足目标湍流度、积分尺度、脉动风速谱及空间相关性等参数的各向异性湍流;讨论了DSRFG方法在生成湍流风场上关键参数的合理取值;(Anisotropic turbulences satisfying the parameters of target turbulence, integral scale, pulsating wind speed spectrum and spatial correlation are synthesized by
