主 题:Meshfree method local support domain moving least square shape function 3D elastostatic behavior complex geometry
摘 要:This study adapts the flexible characteristic of meshfree method in analyzing three-dimensional(3D)complex geometry structures,which are the interlocking concrete blocks of step *** elastostatic behavior of the block is analysed by solving the Galerkin weak form formulation over local support *** 3D moving least square(MLS)approximation is applied to build the interpolation functions of *** pre-defined number of nodes in an integration domain ranging from 10 to 60 nodes is also investigated for their effect on the studied *** accuracy and efficiency of the studied method on 3D elastostatic responses are validated through the comparison with the solutions of standard finite element method(FEM)using linear shape functions on tetrahedral elements and the well-known commercial software,*** results show that elastostatic responses of studied concrete block obtained by meshfree method converge faster and are more accurate than those of standard *** studied meshfree method is effective in the analysis of static responses of complex geometry *** amount of discretised nodes within the integration domain used in building MLS shape functions should be in the range from 30 to 60 nodes and should not be less than 20 nodes.
