Variance-Based Sensitivity Analysis of the Biaxial Test on a Cruciform Specimen

Parameter identification is a key aspect in the modeling of material’s mechanical behavior. The quality depends on sensitivity test results to values constitutive parameters. In this context, variance-based analysis performed, order quantify influence material parameters biaxial cruciform specimen; particular Swift hardening law and Hill'48 anisotropic yield criterion forces, principal strains, strain path thickness reduction. general, it was concluded that forces major value, while anisotropy have most reduction along surface specimen.
