The aim is to evaluate how strain rate changes during creep are related to the time until material failure.
Conducted quantitative measurements of strain rates under various conditions.
Estimated time to failure based on measured creep rates.
Analyzed the relationship using the Monkman-Grant constant.
Found a significant correlation between strain rate changes and estimated failure times.
Established the Monkman-Grant constant as a key factor in extrapolating life to failure.
Abstract
Relationship between the estimated time to failure, t f and under different minimum creep rate, .The Monkman-Grant constant is expressed as the function of . 0.
