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.

Energy release rates of degrading composite structures

19th AIAA Applied Aerodynamics Conference, 2001
Energy release rates during progressive damage and fracture of laminated composite structures subjected to loading are evaluated via computational simulation. A computer model is utilized for the assessment of structural response, progressive fracture, and defect/damage tolerance characteristics.

Energy release rate along a kinked path

Mathematical Methods in the Applied Sciences, 2010
Summary: Considering anti-plane elasticity we provide an existence result for the energy release rate along a piecewise \(C^{1, 1}\) path that admits a kink. We provide two representations: an asymptotic one in terms of the stress intensity factor and an integral one in terms of the Eshelby tensor. Both the formulas make use of an implicit coefficient,

Energy release rates in patched cracked plates

Engineering Fracture Mechanics, 1988
The fatigue and fracture performance of a cracked plate can be significantly improved by reinforcing it with high modulus composite material. The reduction in valid fracture mechanics parameters like energy release rate (G) or stress intensity factor (SIF) is measure of effectiveness of the reinforcement.

Strain energy release rates for turning cracks

Composites, 1972
Abstract The ratio of strain energy release rates for propagation of a crack in its own plane and perpendicular to it has an important effect on the direction of propagation. This ratio is a function only of the relative values of the elastic constants of the material, and the mode of stressing of the crack. The ratio is determined by an experimental

Energy release rates in fire retardant evaluation

Fire Technology, 1970
Rate of spread and other indirect measurements of fire intensity are often used as measures of flammability when fire-retardant chemicals are evaluated under laboratory conditions. The authors describe a system for obtaining the energy release rate directly and show its importance and relation to retardant effectiveness.
