Accuracy improvement for linear tetrahedral finite element by means of virtual mesh refinement / Sugeng Waluyo

This paper offers a new strategy to improve accuracy on deformation field of linear 4-node tetrahedral finite elements (FE) commonly used in computer aided engineering (CAE) software by means of virtual mesh refinement (VMR). Here, the improvement is achieved by embodying additional virtual strain e...
