Target Stress Prediction for Durability Analysis

Abstract

This paper present a methodology to predict target stress under a unit load for a given load schedule, material and geometry analytically. This approach improves the conventional way of doing fatigue and life prediction. This method can be used to any parts/subsystems, which have durability issue. The advantages of knowing the target stress analytically include cost saving in term of hardware reduction and development time saving because the further validation time of design can be shorten. As an example, a decklid global latch design is discussed.
