Dear all ,
I wanted to ask with an example , let us say , we modeling a CT specimen with XFEM , I wanted to ask what is the difference of specifying kinematic coupling between the pins and hole and giving say displacement (as in displacement control) to the pins to giving displacement to the nodes at the hole directly ? What is the difference between both the cases ?
FEM is the conventional finite element method traditionally been implemented in commercial software like ABAQUS and used for most of the quasi-static and dynamic analysis without crack in the geometry whereas ,XFEM (short for, eXtended Finite Element Method) is used to simulate problems involving a pre-existing crack in the geometry and in the background it enriches the solution space of conventional FEM. I hope it answer yours question sir .
