WAVE PROPAGATION OF IMPACTED LAMINATED BEAM

摘要

Direct Mode Superposition Method (DMSM) has been employed to deal with the rigid elastic impact of particle upon laminated beam whose mechanical model is established by making use of. Successive Warping Correction Model (SWCM) and the numerical solutions of the rigid impact problem are obtained by means of Hierarchical Finite Element Method (HFEM), some deep investigations have been carried out about wave propagations of longitudinal and transverse stresses waves.
