On Energy Release Rate for Propagation of a Straight Crack in a Cosserat Elastic Body.

In this paper, we extend some results involving the energy release rate in the case of the propagation of a straight crack in an elastic solid. These results, approached by Gurtin and Yatomi in classical elasticity, are generalized in order to cover a Cosserat-type elastic body. We also investigate the effects of the microinertia and the couple stresses on the energy release rate. [ABSTRACT FROM AUTHOR]
