    Abstract

    The 29th Symposium Swedlow Lecture described the current state of the art of predicitve fracture mechanics tools. Both two-parameter and mechanism-based approaches were reviewed, with emphasis placed on the development of computational cell models. Within their respective regimes of applicability, both approaches are shown to correctly correlate constraint effects on fracture toughness levels.

    Keywords:

    two-parameter fracture mechanics, computational cell models, micromechanics, finite element analysis
