Conservation Laws and Energy-Release Rates

Journal of Applied Mechanics, 1973
New path-independent integrals recently discovered by Knowles and Sternberg are related to energy-release rates associated with cavity or crack rotation and expansion. Complex-variable forms are presented for the conservation laws in the cases of linear, isotropic, plane elasticity.

On energy release rates in Peridynamics

Journal of the Mechanics and Physics of Solids, 2020
Abstract This work is concerned with the calculation of fracture energy release rates in Peridynamics. The existing crack growth criterion and the related damage model in Peridynamics, e.g. the critical bond stretch in the prototype micro-elastic brittle (PMB) material model, are based on the energy release rate of an idealized infinite crack model ...

Energy Release Rates from Hybrid Fuels

Transactions of the ASAE, 1984
ABSTRACT HEAT release patterns of hybrid fuels containing diesel fuel and soybean oil in a microemulsion with ethanol were compared to those of straight diesel fuel. A naturally-aspirated direct-injection diesel engine was used. The hybrid fuels were found to burn faster with higher levels of premixed burning and lower levels of diffusion flame burning

Energy Release Rate in Piezoelectric Media

International Journal of Fracture, 1999
First, some path-independent integrals for piezoelectric media are constructed by considering the gradient of the energy stored in deformation and electric field. Secondly, it is proved that one of the path-independent integrals represents the energy release rate when crack extension happens.

Energy release rate and crack kinking

International Journal of Solids and Structures, 1981
Abstract A closed form solution is presented for the energy release rate at the onset of kinking of a straight crack in an infinite elastic medium subjected to a predominantly Mode I loading. The solution is accurate to the second order of kink angle and is carried out by the method which models the kink as a continuous distribution of infinitesimal ...

Energy-Release Rate in Elastic-Plastic Fracture Problems

Journal of Applied Mechanics, 1981
It 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.

Energy release rate of symmetric adhesive joints

Engineering Fracture Mechanics, 1992
Abstract 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 ...
