Probabilistic lifetime strength of aerospace materials via computational simulation

摘要: The results of a second year effort research program are presented. included development methodology that provides probabilistic lifetime strength aerospace materials via computational simulation. A phenomenological constitutive relationship, in the form randomized multifactor interaction equation, is postulated for degradation structural components propulsion systems subjected to number effects primitive variables. These variables often originate environment and may include stress from loading, temperature, chemical, or radiation attack. This equation computer program, PROMISS. Also calibrate using actual experimental data together with multiple linear regression data.
