Steady-state Crack Growth and Work of Fracture for Solids Characterized by Strain Gradient Plasticity
Mode I steady-state crack growth is analysed under plane strain conditions in small scale yielding. The elastic-plastic solid is characterized by a generalization of JZ flow theory which accounts for the influence of the gradients of plastic strains on hardening. The constitutive model involves one new parameter, a material length 1, specifying the scale of nonuniform deformation at which harde...
متن کاملFracture analysis in the conventional theory of mechanism-based strain gradient (CMSG) plasticity
In a remarkable series of experiments, Elssner et al. (1994) and Korn et al. (2002) observed cleavage cracking along a bimaterial interface between Nb and sapphire. The stress required for cleavage cracking is around the theoretical strength of the material. Classical plasticity models fall short to reach such a high stress level. We use the conventional theory of mechanism-based strain gradien...
متن کاملThe boundary-layer effect on the crack tip field in mechanism-based strain gradient plasticity
The theory of mechanism-based strain gradient (MSG) plasticity involves two material length parameters, namely the intrinsic material length l and the mesoscale cell size lε, which are on the order of a few microns and 0.1 μm, respectively. Prior studies suggest that lε has essentially no effect on the macroscopic quantities, but it may affect the local stress distribution. We demonstrate in th...
متن کاملStrain gradient effects on steady state crack growth in rate-sensitive materials
Steady state crack propagation produce substantial plastic strain gradients near the tip, which are accompanied by a high density of geometrically necessary dislocations and additional local strain hardening. Here, the objective is to study these gradient effects on Mode I toughness of a homogeneous rate-sensitive metal, using a higher order plasticity theory. Throughout, emphasis is on the tou...
متن کاملStatic analysis of rectangular nanoplates using exponential shear deformation theory based on strain gradient elasticity theory
In this research, the bending analysis of rectangular nanoplates subjected to mechanical loading is investigated. For this purpose, the strain gradient elasticity theory with one gradient parameter is presented to study the nanoplates. From the best knowledge of authors, it is the first time that the exponential shear deformation formulation based on strain gradient elasticity theory is carried...
