AB  - The goal of this paper is to develop a computational model for the free vibration analysis of laminated composite shells with embedded delaminations. Laminated composite shells of different shape are modeled using the assembly of layered plate finite elements based on the Generalized Laminated Plate Theory of Reddy. Discontinuities in the displacement field are implemented using the Heaviside step functions. The material is assumed as orthotropic and linearly elastic. The solver is coded in MATLAB. For the generation of models and the visualization of results, GiD Pre/Post Processor is used. After the verification of the proposed model for the intact composite shells using the existing data from the literature, the effect of delamination size on the fundamental frequencies is investigated numerically. A variety of new results for delaminated shells is presented as a benchmark for future investigations.

AB  - In the paper, a simple and efficient algorithm to track a moving delamination front of arbitrary shape, using a laminated finite plate element model in conjunction with the Virtual Crack Closure Technique (VCCT), is proposed. The solution requires the calculation of the virtually closed area in front of the delamination, which is approximated by means of a 6-node-polygon, the delamination opening behind this front and the reaction forces in the nodes at the delamination front. These quantities are calculated in a local coordinate system (LCS) defined in the nodes along the delamination front. Using the proposed algorithm, arbitrary meshes composed of 4- and 9-node quadrilateral finite elements can be considered. The proposed model is developed in the context of a layered finite element plate model. To prevent inter-laminar penetration of adjacent layers in the delaminated region, an algorithm recently proposed by Marjanovic et al. (2015) is adopted. The model performance is demonstrated by re-analyses of the Double-Cantilever-Beam problem, for which analytical solutions exist, and by transient analyses of laminated composite plates with propagating delamination fronts.
