โœฆ Synopsis

A three-dimensional failure criterion is proposed. The criterion relies on a maximum of four parameters, that can be interpreted geometrically in principal stress space. It relates in a natural way the Rankine, the Lade, the Matsuoka-Nakai criterion and the von-Mises criterion. Predictions based on this criterion exhibit very good agreement with experimental data for a variety of materials, in particular considering three-dimensional aspects.

A criterion is developed for determining whether a particular mode of failure is expected to be of ductile type or brittle type depending upon both the material type and the particular state of stressing the isotropic material to failure. The material type is specified by an ฮฑ index obtained from tw

A rationale for internal hydrogen embrittlement failure is constructed from the following elements: (I) stress enhanced hydrogen accumulation; (2) formation of a microerack; (3) precipitation of hydrogen in the microcrack and build up of pressure; (4) attainment of a critical combination of pressure
