Abstract: | This study considers life prediction analysis of high temperature structures. In the case of failure under high temperature cyclic loading, material is damaged by cavity growth and crack propagates along the cavitated grain boundaries with higher growth rate. With this cavity damaging effects, a crack growth model has been developed. Using this model, computer simulation of life prediction has been performed for 304 stainless steel under various loading shapes at high temperatures. |
