摘要
本文介绍了平面弹粘塑性自适应有限元分析软件系统ＡＣＯＲＥ的设计思想，对平面四边形网格自动剖分模块ＧＥＮＣＯＲＥ、时步自适应弹粘塑性有限元模块ＣＯＲＥ以及有限元网格尺度估计模块ＤＥＮＣＯＲＥ的有关理论问题进行了讨论，并给出了一个算例．
The design principle of two-dimensional adaptive elasto-viscoplastic FEM program system ACORE has been described in this paper and the details about the mesh g6neration, the time stepping adaptive in elasto-viscoplastic FEM analysis as well as the mesh she estimation have been discussed. Engineering example of underground opening shows that the ACORE system has the ability to deal with complicated structural problems, it also proves that the adaptive FEM theory has great advantage and expectation in engineering practice.
