Journal ArticleDOI
Family of crack-tip fields characterized by a triaxiality parameter—I. Structure of fields
Noel P. O’Dowd,C. F. Shih +1 more
TL;DR: In this article, a two-parameter fracture mechanics approach for tensile mode crack tip states in which the fracture toughness and the resistance curve depend on Q, i.e., JC(Q) and JR(Δa, Q), is proposed.
Journal ArticleDOI
Family of crack-tip fields characterized by a triaxiality parameter—II. Fracture applications
Noel P. O’Dowd,C. F. Shih +1 more
TL;DR: In this paper, the J-dominance is used to define the size scale over which large stresses and strains develop while Q scales the near-tip stress distribution and the stress triaxiality achieved ahead of the crack.
Journal ArticleDOI
Gradient-dependent deformation of two-phase single crystals
TL;DR: In this article, a slip-system-based constitutive formulation is proposed to account for the additional strengthening mechanism associated with the deformation gradients within a single crystal with a high volume fraction of dispersed inclusions.
Journal ArticleDOI
Finite element implementation of a generalised non-local rate-dependent crystallographic formulation for finite strains
TL;DR: In this paper, the authors describe the finite element implementation of a generalised strain gradient and rate-dependent crystallographic formulation for finite strains and general anisothermal conditions based on a multiplicative decomposition of the deformation gradient.
Journal ArticleDOI
Mixed-mode fracture toughness of ceramic materials
TL;DR: In this paper, an experimental technique whereby pure mode I, mode II, and combined mode I-mode II fracture toughness values of ceramic materials can be determined using four-point bend specimens containing sharp, through-thickness precracks is discussed.
