摘要
文［１］推出了求解不连续介质体的界面应力元法，并在理论和实例验算两方面论证了该法具有精度好、效率高、适用范围广等优点。通过进一步研究，该法还可适应任意网络离散模型的计算。本文引用自然坐标，实施了任意形状单元的界面元算法，并给出了算例，成果表明，本文的算法可行，其精度也是令人满意的。
Interface Stress Element Method (ISEM) for solving non-continuous medium problems has been formed in paper.It has been broadly used and has been proved to have high accuracy and efficiency both in theory and in application. With further study, ISEM could also be used in calculation of discrete model with elements of arbitrary shape. Using natural coordinate, algorithm of ISEM for elements of arbitrary shape has been performed. Numerical examples given in this paper show that the algorithm is feasible and its accuracy is satisfactory.
