Description

High strength safety critical parts may show localized high stress areas that exceed the yield or ultimate strength when evaluated with finite element analysis (FEA) methods. The feasibility of developing FEA methods to accurately predict part failures with localized stress concentrations will be demonstrated. Linear elastic, nonlinear plastic, implicit and explicit FEA methods will be developed and evaluated. Proof-of-concept test coupons will be manufactured and tested to failure. The FEA failure prediction results will be compared to the test results to validate the FEA methods and demonstrate feasibility. The results will be the basis for an industry standard for FEA failure prediction and FEA stress concentration interpretation.
