Effect of delamination face overlapping on strain energy release rate calculations

Composite Structures, 1992
Abstract The strain energy release rate is often used as a fracture mechanics parameter to describe delamination propagation and onset in composites, and is conveniently evaluated using finite element analysis. A common problem encountered in analysis is overlapping (interpenetration) of the delamination faces if these faces are not constrained. This

A parametric study on strain energy release rates of compression members

Composite Structures, 1989
Abstract The objective of this paper is to assess the delamination growth subsequent to sublaminate buckling in composite laminates by evaluating the strain energy release rates. Laminates under a wide range of compressive loads, different material properties and stacking sequences are parametrically and experimentally studied.

Strain-energy release rate of delaminated composite plates using continuous analysis

Composites Engineering, 1994
Abstract A continuous analysis procedure is introduced for determining the strain-energy release rate for composite plates containing arbitrarily located delamination regions of arbitrary shapes. The plates are considered to be simply supported along their four edges, and double Fourier series solutions are used.

Circular Delaminations - the Effect of Thermal Strains on the Strain Energy Release Rate

Mechanics of Composite Materials, 2001
The analysis presented focuses on the extent to which the thermal loading resulting from a difference between the curing and service temperatures and from variations in the thermal-expansion coefficients from layer to layer can affect the growth of delaminations. Square laminate plates containing circular delaminations are examined.

Finite Element Analysis of Strain Energy Release Rate at Delamination Front

Journal of Reinforced Plastics and Composites, 1991
This study examined the delamination initiation of two-lamina composite laminates under central loading. A three-dimensional finite element program was devel oped to calculate the interlaminar stresses. In order to simplify the numerical analysis, an interfacial layer was embedded in between the composite laminae.

Efficient Computation of Strain Energy Release Rate in Crack Growth Simulation

Durability and Damage Tolerance of Composite Materials and Structures, 1999
Abstract This paper utilizes an automated process to simplify the calculation of the strain energy release rate (SERR) during the crack propagation. The convergence of a finite element solution is achieved by adaptive re-meshing scheme with an error estimator of the linear strain triangular (LST) elements.

The Effect of Local Yielding on the Strain-Energy Release Rate

Journal of Basic Engineering, 1969
In a recent paper in the Journal of Basic Engineering [1], Forman presented numerical results for the strain-energy release rate of a crack in a finite width plate using the Dugdale model [2] of a yielded crack to describe the effects of local plastic flow. However, there appear to be several errors in the formulation of the problem by Forman.
