Abstract

Abstract

The weak interfacial bonding seriously affected the mechanical behavior of laminated plates. Different imperfect bonding models of laminated plates were discussed in Hamilton canonical equation. By combining the modified HR variational principle for elastic material with the quadratic interpolation functions, the linear formulation of laminated plates with 8node for Hamilton canonical equation in the Cartesian coordinate was derived. The relationship between stress and displacement on the interface between layers was considered to improve the normal bonding model, and the state equation with delamination situation was established. The stress and displacement were obtained by solving the overall model. Numerical examples showed that the methods presented were correct, and this paper studied the linear and nonlinear bonding models of the laminated plate respectively. The last results show that the application of improved models can simulate the process of fail better.
