TLDR
In this paper, the behavior of laminated plates subjected to bending is analyzed when the center lamina contains a through-crack and the effects of crack size and longitudinal and transverse moduli on the stress intensity factor were evaluated.Abstract:

Stress analysis around circular holes in FRP laminates under transverse load
T.K. Paul,K.M. Rao +1 more
TL;DR: In this paper, the finite element method along with Lo-Christensen-Wu higher order bending theory is used for evaluating stresses and stress concentration factor due to a circular hole in fibre reinforced composite laminates subjected to transverse loads.

Influence of crack closure on the stress intensity factor for plates subjected to bending—A 3-D finite element analysis
TL;DR: In this paper, the impact of the crack closure on the variation of the stress intensity factor across the plate thickness is analyzed for both finite and infinite plate geometries for a 3D finite element method employing three-dimensional degenerate solid element.

Three-dimensional finite element analysis of cracked thick plates in bending
TL;DR: 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.

An approximate three-dimensional theory of layered plates containing through thickness cracks
Robert Badaliance,G.C. Sih +1 more
TL;DR: In this article, a variational principle of minimum complementary potential energy is employed to obtain a system of partial differential equations and associated boundary conditions which govern the in-plane variation of the stress field.

Stress intensity factor for a three-layered plate with a crack in the center layer
E.P. Chen,G.C. Sih +1 more
TL;DR: In this article, the authors model the laminated composite as a multilayered plate each layer being made of a different material and develop a laminate plate theory by application of the minimum complementary energy theorem in variational calculus such that the qualitative threedimensional character of the crack edge stresses is retained while approximations are made in a quantitative sense on the stress intensity factor.

Three-Dimensional Analysis of Laminar Composites with Through Cracks

TL;DR: In this paper, the variational principle of minimum complementary potential energy is employed to develop an approximate three-dimensional model for the stress distribution in laminar composites, which is applied to the problem of a symmetric composite plate containing a through crack subjected to in-plane loading.
