Dynamic Response of Anisotropic Laminated Plates under Initial Stress to Impact of a Mass.
Abstract
The central impact of a mass on a simply-supported laminated composite plate under initial stress is investigated. The contact force and the dynamic response of the plate are obtained by solving a non-linear integral equation. The energy transferred from the mass to the plate during impact is also obtained by use of a normalized contact force. It is found that a higher initial tensile stress elevates the maximum contact force, but reduces the contact time, the deflection, and the stresses. It is also noted that a higher tensile initial stress results in less energy transfer from the striking mass to the plate.
