Failure-Mechanism Models For Creep And Creep Rupture
J. Li, and A. Dasgupta
This tutorial illustrates design situations where creep and creep rupture
of components system performance over time, thereby acting as a wearout
failure mechanism. Polycrystalline materials, such as metals &
ceramics, and polymers are treated. Analytic microstructural creep
mechanisms leading to failure of these materials are presented. Continuum
microscale models for predicting long-term creep are explained for practical
design purposes. Two examples illustrate these models for mechanical
engineering and electronic packaging situations.
