Abstract:
The Wave Based Method (WBM) belongs to the family of indirect Trefftz methods and uses weighted wave functions in order to model boundary value problems. These wave functions have to satisfy the underlying differential equations and usually violate the boundary conditions of a WBM element. A weighted residual formulation permits to minimize this error by determining the weighting factor for each wave function. By applying the WBM to a 2D saturated soil structure, the propagation of two longitudi...     »
