Formability of aluminum 1050A at high temperatures: Numerical modeling and experimental validation

Abstract The sheet metals are prone to large plastic deformation during forming processes. study purpose is investigate 1050A aluminum sheets thermomechanical behavior with ductile damage. A modified Swift model coupled isotropic damage and thermal effects was used. parameters introduced using coefficients Erichsen index. An inverse identification procedure applied non-homogeneous test results. Bulge then used validate the identified parameters. (Punch force vs displacement) results were obtained by experimental testing simulation build objective function. Aluminum plasticity flow variables a part of remaining bulge for validation. numerical approach allowed detection failure zones respect gradient induced heat exchange. Within isothermal condition, equivalent stresses strains simulations data.
