Inclusion of DSA Modeling Capability in Unified Viscoplasticity Theories, with Application to Incon is Dynamic Strain Ageing (DSA). The modeling of DSA within the context of unified theories of viscoplasticity is studied in this paper. In particular, an algorithm is proposed to include DSA modeling capability in Chaboche’s theory. In doing so, use is made of the so-called “correction function” pr

The equations reviewed are generalization of the internal stress concept and use two internal state variables; namely the drag stress and the back stress variables.

The results indicated that the initiation of fatigue cracks are insensitive to the notch severity and to the aging condition of the matrix. The overaging he

The effects of crack closure are discussed as is also the effect of an overload as influenced by ΔK level and thickness. The process referred to as anomalous crack growth is considered in terms of the development of crack closure in the wake of a newly formed fa

Processing Defects and the Fracture of Ceramics and Designed Ceramic/Ceramic Composites,and. several fracture origin types were identified. These defects were then classified via their response to various elimination techniques. An elliptical crack model was used to characterize the correlation between fracture stress and fracture origin size. Consistent results showed that an order-of
