Free vibration analysis of a laminated beam with delaminations is presented using a layerwise theory. Equations of motion are derived from the Hamilton's principle, and a finite element method is developed to formulate the problem. Numerical results are obtained and compared with those of other theories addressing the effects of the lamination angle, location, size and number of delamination on vibration...
This paper presents a solution procedure for three-dimensional (3D) simulations of delamination phenomena in composite materials. The procedure is based on a constrained Newton-Raphson method and uses an iterative algorithm to solve the linearised systems of equations. We will show that this procedure can be used effectively for simulating the free edge delamination of a 3D composite plate. We will...
