Effect of stitching on Mode I strain energy release rate
Composite Structures, 2005Abstract Stitching advanced graphite/epoxy composites in the through-thickness direction improves the interlaminar fracture toughness. The Mode I energy release rate of a graphite/epoxy composite, with and without stitching fibers, was experimentally determined using double cantilever beam specimens.

Strain energy release rates in straight and curved notched compositebeams
32nd Structures, Structural Dynamics, and Materials Conference, 1991Two-dimensional finite element modeling has been used to determine strain energy release rates for delamination cracks in straight and curved notched tensile beams. The notched tensiie beam is a low-order analog of a cylindrical pressure vessel with an external part-through hole.

Nonlinear Approach for Strain Energy Release Rate in Micro Cantilevers
Volume 10: Micro and Nano Systems, 2010An analytical Mixed Mode I & II crack propagation model is used to analyze the experimental results of stiction failed micro cantilevers on a rigid substrate and to determine the critical strain energy release rate (adhesion energy). Using nonlinear beam deflection theory, the shape of the beam being peeled off of a rigid substrate can be ...

Strain-Energy Release Rate Analysis of Plates with Postbuckled Delaminations
Journal of Composite Materials, 1989Delamination growth due to local buckling of a delamination was studied. Delamination growth was assumed to be related to the total strain-energy release rate, G. In order to calculate the distribution of G along the delamination front, a virtual crack closure technique was developed which is suitable for use with plate analysis.

Strain energy release rate for interfacial cracks between dissimilar media
Engineering Fracture Mechanics, 1976Abstract An analysis was made of the stresses along a bonded interface between two elastic half spaces of dissimilar isotropic materials. Various loading conditions which give rise to interfacial crack propagation were considered, including thermal loads, bending loads and tensile loads parallel to the bond. From this two-dimensional stress analysis,

Determining buckling strain energy release rate through indentation-induced delamination
Thin Solid Films, 2011An oscillating indentation load was applied to delaminate a diamond-like-carbon film from a silicon substrate. After delamination occurred, a two-stage behavior was exhibited in the load-depth results; then, a three-stage behavior was exhibited after buckling occurred due to a long enough delamination length.

Strain Energy Release Rate in Treated Circumferentially Cracked Spring Steel
International Journal of Manufacturing, Materials, and Mechanical Engineering, 2012The suspension system is a prominent piece of material that plays a vital role in the stability of a vehicle. During the service, the suspension system is subjected to different environmental conditions, at the same time it has to sustain a variety of loads.

Strain energy release rates for internal cracks in rubber blocks
International Journal of Fracture, 1993Strain energy release rates have been calculated by Finite Element Analysis (FEA) for growth of a small crack in a cylindrical rubber block under tension. The crack was assumed to lie in the center of the block in a plane perpendicular to its axis. The rubber was taken to be virtually incompressible in bulk and non-linearly elastic.
