ANALYTICAL FORMULATION TO PREDICT TIME TO FAILURE OF THE STRESS CORROSION CRACKING

Abstract

This work presents an Analytical model to predict the time to failure of the stress corrosion cracking (SCC) using laboratory experimental data that related stress intensity factor (K) to crack growth rate (V). Current analysis has been implicated on austenitic stainless steel in 42% chloride magnesium (MgCl2) at 154 oC and the results were in agreement with the experimental recorded data. The present analysis generates very beneficial information about the mechanical and environmental effects on the failure of specific environment and this information is difficult to be obtained from laboratory experiments.
