Impact of Prior Loading on the Reliability of Safety Critical Systems


Article Preview

Probabilistic models are developed to determine changes in the survival probability particularly when prior loading contributes to changes in residual stress and fracture toughness. Experimental evidence for variations in toughness and residual stress is examined and then incorporated into probabilistic models. The structure’s reliability is consistently better after prior loading.
