Nonlinear meshfree formulation of nonlinear geometric composite beam with slip

Meshfree (MFree) method is one of the latest numerical techniques after the established Finite Element Method (FEM), Finite Difference Method (FDM) and Boundary Element Method (BEM). Therefore, MFree method is still in its early development stage where many practical engineering problems are still h...
