Growth of Cracks By Intergranular Cavitation in Creep

A Damage Mechanics Model for Creep and Oxygen Embrittlement in Metals

“…In particular, the parameters n, 0 , and _ " " 0 are based on the data accumulated by Argon et al (1992). The creep damage parameters !…”

“…The present model developed earlier is now applied to the steady-state and tertiary creep deformations of two materials without the SAGBO behavior: (a) Type 304 stainless steel tested by Swindeman (see Argon et al, 1992) at 760 C and (b) tough pitch copper tested by Dyson (see Argon et al, 1992) at 250 C. Relevant parameters in the present model for each of the two materials are given in the second and third columns of Table 1. In particular, the parameters n, 0 , and _ " " 0 are based on the data accumulated by Argon et al (1992). The creep damage parameters !…”

Preparation and characterization of nanocomposites based on polylactide manufactured by reactive extrusion-calendering : thermal, rheological, mechanical and fracture properties

“…It is also notice that the voids were small and were mostly present in the vicinity of the crack tip. These voids formation could be ascribed to the typical high crack-tip stress triaxiality and lower measure of toughness during the initial loading state (Argon et al, 1992). Additionally, formation of multiple ridges parallel to the crack propagation direction coupled with massive elongated voids were also observed in PLA -C (highlighted in red rectangle).…”
