Enhancement based on conventional FEM​

Galerkin framework

Mesh-based formulation

Adaptive procedure

  • Deal with mesh distortion

  • Improve mesh quality

  • Large deformation analysis

  • No material failure

Nodal enrichment of POU 

  • Allow arbitrary crack propagating into element

  • Heaviside function to introduce strong discontinuity

  • Phantom element for numerical integration

Meshfree enrichment

  • Extra node in finite element

  • Conforming meshfree shape function within element 

  • Enrich the approximation field to relieve volumetric locking
