Abstract This paper attacks a long-time challenge in industry application and provides a physics-based exploration and modeling for system level thermal apparent activation energy when multiple independent components or competing failure modes are present under steady-state thermal stressing and each is governed by its own thermal activation energy and its own underlying Weibull life distribution.
