Patent ID: 8768660

Claim:
A method of numerically simulating structural behaviors of an embedded bi-material, said method comprising: receiving, in a computer system having one or more application modules configured for simulating structural behaviors of an embedded bi-material installed thereon, a configuration of an embedded bi-material that contains a base material and at least one immersed material; independently creating first and second computerized grid models from the received configuration by said one or more application modules, said first computerized grid model representing the embedded bi-material in its entirety and said second computerized grid model representing the immersed material; deriving a set of interface nodes from said second computerized grid model by said one or more application modules, said set of interface nodes defining a material interface between the base material and the immersed material; creating a first group of meshfree nodes representing the embedded bi-material by said one or more application modules, said first group of meshfree nodes being derived from said first and said second computerized grid models; designating those of the first group of meshfree nodes located within a space bordered by the material interface as a second group of meshfree nodes by said one or more application modules; and obtaining simulated structural behaviors of the embedded bi-material by said one or more application modules using said first and said second groups of meshfree nodes with a meshfree method that combines results of at least first and second meshfree approximations, said first meshfree approximation covering said first group of meshfree nodes and basing upon said base material's properties while said second meshfree approximation covering the second group of meshfree nodes and basing upon a property differential between said immersed material and said base material.
