Resumé

Validation of creep damage constitutive equations under the future loads, the left over lifetime is predicted to be quite limited. The main objective is to make prediction about the lifetime left because a growing stage of damage is encouraged by the previous history of loading. The ultimate goal is to render a loading spectrum that is complete in nature and predict about the time of keeping the material in the loading sequence, prior to facing any complexities related to catastrophic failure. All these damages and lifetime conditions are considered as responsible factors under a specific condition that is termed as ‘creep failure condition’. This kind of creep failure condition matches with the enveloped polymers, as well as, with other high temperature conditions.Cite this ArticleSaad Kalfalla, Meshaal Sulieman,Makhtar Alreahe.
