Abstract:
1. A method of performing a mesh-free analysis of a general three-dimensional structure, the method comprising: defining a plurality of nodes representing the general structure in a computer system having a mesh-free analysis application module installed thereon; choosing a mesh-free approximation scheme to be used in the mesh-free analysis application module; constructing a set of original mesh-free shape functions based on the chosen mesh-free approximation scheme; when the original shape function is lack of Kronecker delta properties, converting the original shape function to a first transformed mesh-free shape function; otherwise designating the original shape function as the first transformed mesh-free shape function, such that the first transformed mesh-free shape function always possesses the Kronecker delta properties; selecting a low pass filter function; creating a second transformed mesh-free shape function by applying only the low pass filter function to the first transformed mesh-free shape function; and performing a mesh-free analysis of the general structure in the computer system using a low-order integration rule in the mesh-free analysis application module, wherein the mesh-free analysis's results are stored to a storage device coupled to the computer system for assisting a user to make decision in improvements of the general structure.
