基于有限变形理论——S-R和分解理论，以悬臂梁弹性大变形为例，建立伽辽金无网格法程序。该程序经过修改可以适用于三维弹性大变形问题的数值求解。(Based on the S-R decomposition finite deformation theory, the Galerkin meshless procedure is established by taking the elastic large deformation of the cantilever beam as an example. The program can be applied to the numerical solution of three dimensional elastic large deformation problems by proper modifications.)
