This work is dedicated to the Weak Trefftz Discontinuous Methods, an extension of the Variational Theory of Complex Rays (VTCR), for the resolution of frequency vibrations of composite structures. This Weak Trefftz Discontinuous Methods allows one to build easily hybrid finite element / Trefftz strategies. Numerical illustrations are presented.
