摘　　要：介绍了使用开发的软件TransMesh和商业化有限元软件ABAQUS,对二维异质体材料微观组织结构进行面向对象的有限元网格划分技术.运用C语言和Python脚本语言,在有限元软件ABAQUS中成功地再现了二维异质体材料微观组织结构的体积代表单元(RVE).并通过软件TransMesh 实现了参数化有限元网格划分.将ABAQUS与自主开发的TransMesh软件相结合,在国内率先系统地掌握了二维异质体材料微观组织结构的有限元网格划分技术,为微观组织结构的有限元模拟的顺利进行奠定了基础.A meshing technique was presented in details,which is developed with software TransMesh developed and commercial finite element software ABAQUS,and is able to mesh complex microstructures of heterogeneous materials in an object-oriented manner.The technique,making use of C and Python code compiling languages and embodied via the software TransMesh,succeeds in constructing representative volume elements (RVE) for two-dimensional complex microstructures of the heterogeneous materials in AB-AQUS environment and provides further the function to mesh specifically in terms of given mesh parameters.It lays an efficient base for finite element meshing of microstructure of heterogeneous materials.
