In the present work, a probabilistic framework for fatigue life prediction and reliability assessment of an engine high pressure turbine disc is proposed to incorporate the effects of load variations and mean stress, which provides a reference for ...

Creep Crack Initiation and Propagation: Fracture Mechanics and Local Approach
Both the initiation and the propagation of macroscopic creep cracks have been studied in 316-L austenitic stainless steel, and, for comparison purposes, in 2219-T851 aluminum alloy. These alloys are, respectively, creep-ductile and creep-brittle.

Basic modelling of creep rupture in austenitic stainless steels
Creep rupture can happen in two ways, brittle and ductile creep rupture. Brittle creep rupture of austenitic stainless steels proceeds with the nucleation, growth and coalescence of grain boundary cavities.

Computer simulation of wear and rolling contact fatigue
A ductile material subjected to repeated rolling contact can accumulate very high levels of shear strain near the surface. At some point the material loses its integrity and fails, and this failure is manifested in the form of wear (the material ...

Multi-axial creep-fatigue life prediction considering history-dependent damage evolution : a new numerical procedure and experimental validation [PDF]
In this paper, a new numerical procedure based on a cycle-by-cycle analysis has been constructed for creep-fatigue behavior and life prediction of high-temperature structures under multi-axial stress states.
