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.

The Strain Energy Release Rate of Composite Microcracking: A Variational Approach

Journal of Composite Materials, 1989
A variational analysis approach has been used to determine the two- dimensional thermoelastic stress state in cross-ply laminates of type [0 m/90 n] s and [90 m/ 0 n] s. The stress analysis was used to calculate the energy release rate due to formation of a new microcrack. The analysis accurately includes the effect of residual thermal stresses. When

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.

Calculation of Stress Intensity Factors Based on Strain Energy Release Rate

2003
Consider a long strip of height 2h and thickness B with a crack of length 2a subjected to a uniform stress σ along its upper and lower faces (Figure 1). For a » h use elementary analysis to determine the stress intensity factor at the crack tip.
