Non-linear progressive failure analysis of laminated composite plates
TLDR
In this article, a progressive failure algorithm is developed where the Generalized Layerwise Plate Theory (GLPT) of Reddy is used for the kinematic description and the material is modeled as a stable progressively fracturing solid.Abstract:
A progressive failure algorithm is developed where the Generalized Layerwise Plate Theory (GLPT) of Reddy is used for the kinematic description and the material is modeled as a stable progressively fracturing solid. The geometric non-linearity is taken into account in the von Karman sense, and the extensibility of transverse normals is included in the finite element formulation. The progressive failure algorithm is used to study the effect of the geometric non-linearity, span-to-depth ratio, lamination sequence and the boundary conditions at the supports on the first-ply and the ultimate failure loads of composite laminates in bending. In addition, a new stiffness reduction scheme is proposed, in which stiffness properties of the failed element is reduced gradually, resulting in partial unloading depending on the amount of damage it accumulates.read more
