Abstract:

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.
