The response in constrained shear of materials characterized by discrete Shear Transformation Zone (STZ) plasticity is investigated. A plane strain strip of finite thickness is analyzed within a small deformation framework and with the STZs modeled a

We consider the maximum value of the magnitude of transformation strain for an Eshelby inclusion set by the requirement of non-negative dissipation. The general formulation for a linear elastic solid shows that the dissipation associated with a strai

The effect of strong toughness heterogeneities on the macroscopic failure properties of brittle solids is investigated in the context of planar crack propagation. The basic mechanism at play is that the crack is locally slowed down or even trapped wh

Vasoya et al. (J. Appl. Mech., 86, 051005, 2019) gave a general expression for the dissipation associated with a single transforming Eshelby inclusion in a linear elastic solid and showed that requiring the dissipation to be non-negative provides a s

International audience; Crack pinning by heterogeneities is a central toughening mechanism in the failure of brittle materials. So far, most analytical explorations of the crack front deformation arising from spatial variations of fracture properties

Metal–ceramic composites produced by melt infiltration of ceramic preforms are studied in an optimal design context. The ceramic preforms are manufactured through a process of freeze-casting of Al2O3 particle suspension. The microstructure of these

International audience; In a recent paper (Leblond et al., 2012), we established, using some results of Rice (1989), the second-order expression of the variation of the mode I stress intensity factor resulting from some small, but otherwise arbitrary
