In recent decades, many studies have been done on combining the finite element (FE) method with meshfree methods, but there is few research on combining the finite strip (FS) and mesh-free methods. Therefore, in this thesis, the combination of the Keywords : Finite strip method, Eelement free Galerkin method; Coupled element free Galerkin-finite strip method; Lagrangian multiplier method; Penalty function method.
