| Abstract Scope |
A methodology is described for obtaining an optimum biaxial cruciform specimen design for aluminum 6000 series alloys. It uses an approach that combines equibiaxial tensile test data with finite element (FE) analysis in conjunction with the application of a robust mathematical optimization strategy. The methodology involves: a) determination of an initial approximate specimen design from literature review, b) development and verification of the initial FE model, c) optimization of the maximum strain and strain uniformity in the gauge area, d) fabrication of a specimen with the optimum configuration and performing an equibiaxial tension test and development of an equivalent FE model, and e) validation of optimized FE model by comparing predicted model optimization improvement results against measured improvements. Using this approach enabled optimum design of a cruciform specimen geometry to maximize the strain achievable in the gauge area while retaining the necessary strain uniformity levels within given physical constraints. |
