On Energy-Release Rates for a Plane Crack

Journal of Applied Mechanics, 1981
Considered is a plane crack in a homogeneous, static stress field. The component of the Ji integral normal to the plane of the crack (J2) is shown not to be path-independent in the sense of the well-known J integral (≡ J1) parallel to the plane of the crack. The relation between the energy-release rate for rotation L and the integral J2 is established.

On the Estimation of Energy Release Rates

Journal of Applied Mechanics, 1983
The energy release rate associated with the Mode I and Mode III crack problems for an infinite, nonlinearly elastic, incompressible body are estimated. The calculation adopts an approximation that is a natural extension of the small-scale yielding concept to problems involving moderate levels of loading.

Energy release rate of moving circular-cracks

Engineering Fracture Mechanics, 2019
Abstract The behavior of fast straight-cracks in brittle, linear-elastic solids was described exactly nearly half-a-century ago by Freund. However, the subsequent attempts to describe analytically the velocity and the energy release rate of fast circular-cracks predicted behaviors which were inconsistent with the observed, experimental evidence.

Pointwise energy release rate in delaminated plates

AIAA Journal, 1995
A laminated plate theory suitable for analyzing delaminations has been derived. The theory is used to study the interaction between the top and bottom sublaminates in the intact region of a delaminated plate. Expressions are derived for the jump in force and moment resultants that occur across the delamination front.

Fracture energy release rate of adhesive joints

International Journal of Adhesion and Adhesives, 1989
Abstract This study was directed towards developing a criterion for estimating the interface separation load for adhesive joints of two dissimilar materials, and comprised the evaluation of the strain energy release rate as such a criterion. A finite element model was used in which attention was focused on Mode I and II failures and a mixed mode ...

On the application of energy release rates

Composites Part A: Applied Science and Manufacturing, 1997
The limits of applicability of the substitution of strain energy for potential energy in energy release rate calculations for Griffith cracks are identified, a discussion notably absent from textbooks. It is also shown that the strain energy change is not adequate to predict the growth of a Griffith crack, and may actually be zero while the potential ...

Energy release rate of dynamic delamination

Engineering Fracture Mechanics, 1994
Abstract The energy release rate of dynamic delamination of plates is derived. The expression is given in terms of jumps of the mechanical fields near the delamination front, and is essentially a form of dynamic energy momentum. Non-linear kinematics of von Karman plate theory are used, together with non-linear elastic material response.

Energy Release Rates in a Fiber-Reinforced Strip

Journal of Applied Mechanics, 1987
This paper discusses Mode I fracture of a semi-infinite crack in a strip of fiber-reinforced material. The crack is opened by point forces applied to the crack faces. The problem is solved using two models for fiber reinforcement; these models are known as the inextensible and idealized theories and are both based on simplification of the equations of ...

Wood Welded Connections: Energy Release Rate Measurement

Journal of Adhesion Science and Technology, 2008
The energy release rates of beech specimens bonded by linear friction welding were determined using double cantilever beam (DCB) tests. The analysis of the results was carried out with the experimental compliance method, which is based on the linear-elastic fracture mechanics.
