摘要
针对基于滑动最小二乘法的板弯曲无单元法进行研究.通过弹性地基板的具体算例,探讨了不同节点的分布方案与指数型权函数影响域大小对板挠度和内力计算精度的影响,并给出了合理布置节点的方案.其对于板弯曲无单元法的进一步研究与应用,具有积极的意义.
A Plate_bending element_free method, which is based on the moving least squares (MLS) interpolants, is studied in this paper. By the numerical examples on elastic foundation plate, the influence of the different nodes distributing and the side of the domain of influence of the exponential weight function on the accuracy of deflection and bending moment is analyzed. The results show that it is significant for the further research and application on the element_free method.
