This paper analyses composite laminate failure mode under various environmental conditions. The FRP laminate is subjected to forced vibration. The composite laminate of CRFP, GFRP, and KFRP has been compared for better utilization of composites. The laminate is made up of three-layer sequence [90/45/0]. The delamination occurs between second and third layers of the laminate modeled using the layerwise theory. The frequency response analysis of the composite plate is performed under bending and twisting loads and the response of the plate in terms of impedance and transverse velocity is measured at different points on the plate. The finite element simulation is carried out using COMSOL Multiphysics® tool. The impedance at any point in the structure under forced vibration is calculated as the ratio of the force to the velocity of that point. At lower frequencies, there is no much changes in the impedance level. At higher frequencies, the impedance of the delaminated plate is deviated from the intact plate. This gives the ample guidance to identify the structural impedance using non-destructive testing (NDT) techniques using high frequency waves. |
