摘要 无网格局部边界元法是一种真正的无网格方法。本文推导了弹性力学问题的局部边界积分方程,并且基于MLS近似方法实现了无网格离散,得出无网格局部边界元法的二维弹性力学问题的格式,推导了修正的基本解,并利用编制的计算程序,应用于实际算例。 Local Boundary Integral Equation(LBIE) for elasticity is derived. The moving least-square(MLS)approximation is used to build the discrete format of the Meshless Local Boundary Element Method. Correctional fundamental solutions are also worked out and added in. The computer program is applied in two typical examples.
