In this paper the behavior of laminated plates subjected to bending is analyzed when the center lamina contains a “through-crack.” The effects of crack size and longitudinal and transverse moduli on the stress intensity factor were evaluated. © 1985, Sage Publications. All rights reserved.

Laminated Plate with an Embedded Through-Crack in the Central Layer

Journal of Reinforced Plastics and Composites

Plates with central through cracks subjected to bending is analysed taking into account the closure of the crack faces on the compression side. A three-dimensional finite element method employing three-dimensional degenerate solid element is used for the analysis. The crack faces have been modelled such that they come in contact over an area on the compression side and interfere with each other. The influence of the crack closure on the variation of the stress intensity factor across the plate thickness is obtained for finite and infinite plate geometries. © 1983.

Influence of crack closure on the stress intensity factor for plates subjected to bending-A 3-D finite element analysis

By using the finite element technique, stress intensity factors have been obtained for finite rectangular plates and the results have been given for various h/a, W/a and L/W ratios. By using a three‐dimensional isoparametric element, the problem has been considered as a three‐dimensional one and the variation of stress intensity factor across the plate thickness has been found to be nonlinear.
