Abstract

Abstract

Based on a constitutive law which includes the shear components of transformation plasticity, the asymptotic solutions to near-tip fields of plane-strainmode I steadity propagating cracks in transformed ceramics are obtained for the case of linear isotropic hardening. The Stress singularity, the distributions of stresses and velocities at the crack tip are determmed for various material parameters. The factors influencing the near-tip fields are discussed in detail.
- transformation toughening ceramics,
