Energy release rate of symmetric adhesive joints
Engineering Fracture Mechanics, 1992Abstract A formula is derived for the mixed mode energy release rate of adhesive joints in terms of local stress concentrations σmax and τmax determined by beam theory. The formula G= 1 2 t E′ a σ 2 max 1 2 t G a τ 2 max is equivalent to a similar expression from two-dimensional elasticity ...

Energy release rate for cracks in finite‐strain elasticity
Mathematical Methods in the Applied Sciences, 2007AbstractGriffith's fracture criterion describes in a quasistatic setting whether or not a pre‐existing crack in an elastic body is stationary for given external forces. In terms of the energy release rate (ERR), which is the derivative of the deformation energy of the body with respect to a virtual crack extension, this criterion reads: if the ERR is ...

Energy Release Rates in a Fiber-Reinforced Strip
Journal of Applied Mechanics, 1987This 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 ...

Energy-Release Rate in Elastic-Plastic Fracture Problems
Journal of Applied Mechanics, 1981It is shown that the energy-release rates associated with the translation, rotation, self-similar expansion and distortion of the fracture process region are expressed by the newly introduced integrals, Jˆ, Lˆ, Mˆ, and Iˆ. These integrals can be defined even if there exist plastic deformation, thermal strains, body forces, and inertia forces.

A theory for the mixed energy release rate
Engineering Fracture Mechanics, 1985Abstract In this paper a review of three mixed energy release rate criteria, which were suggested by Hussain et al., Tract. Anal. ASTM560, 2–28 (1974), Nuismer, Int. J. Fract.11, 245–255 (1975) and Wang, Fracture 1977, Vol. 4, pp. 135–154, University of Waterloo (1977), respectively, is made.

Energy release rate of dynamic delamination
Engineering Fracture Mechanics, 1994Abstract 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.

On the Energy Release Rate in Finite–Strain Elasticity
Mechanics of Advanced Materials and Structures, 2008Griffith's fracture criterion describes in a quasistatic setting whether or not a pre-existing crack in an elastic body is stationary for given external forces. This fracture criterion can be reformulated in terms of the the energy release rate (ERR), which is the derivative of the deformation energy of the body with respect to a virtual crack ...

Analysis of energy release rate for cracked laminates
Applied Mathematics and Mechanics, 1995The aim is to prove the existence of energy release rate components for cracks between two fairly general anisotropic media. A relationship between the energy release rate components and stress intensity factor is discussed. Classical plate theory is used to obtain the expressions for the energy release rate components.

Energy release rate for cracks in ideal composites
International Journal of Solids and Structures, 1977Abstract Infinitesimal plane deformations of ideal fiber-reinforced composites with elastic shearing stress response are considered. The fibers are straight and parallel, and there is a straight crack perpendicular to the fibers. A general expression for the energy release rate per unit length of crack advance is obtained.
