Large Reference Displacement Analysis of Composite Plates. Part 1. Finite ElementFormulation

摘要

This investigation concerns itself with the dynamic analysis of thin, laminatedcomposite plates consisting of layers of orthotropic laminae that undergo large arbitrary rigid body displacements and small elastic deformations. A non-linear finite element formulation is developed which utilizes that assumption that the bonds between the laminae are infinitesimally thin and shear non-deformable. Using the expressions for the kinetic and strain energies, the lamina mass and stiffness matrices are identified.
