摘要: The four modes of vibration an isotropic rectangular plate with inclined crack are investigated. It is assumed that the remains continuous and its center located at plate. governing nonlinear equation transverse boundary conditions being simply-supported on all edges developed. multiple scale perturbation method utilized as solution procedure to find steady-state frequency response equations for vibration. free forced vibrations derived their responses presented. A special case large-scale excitation force has also been considered. parameter sensitivity analysis angle crack, length position external applied performed. shown according aspect ratio plate, can have either hardening effect or softening behavior.
