Elastic Responses of a Composite Shell Structure Subjected to Impact Loading

Received 17 December 2019; accepted June 2020
 This work investigated the elastic responses of a composite laminate shell subjected to transverse low-velocity impact. The governing equation based on equations motion both impactor and target was developed detetrmine impact force. displacement unit impulse loading solved using finite element method. A non-linear differential in terms indentation depth derived by incorporating Hertzian contact law theory convolution. Runge-Kutta method employed solve integro-differential equation, leading determination force at point between shell. including stress were evaluated exerting apex Present approach verified with analytical, experimental numerical results reported existing literatures. influences stacking sequence examined through series parametric studies. In addition, spherical shells different materials such as steel, aluminum glass studied.
