Abstract

•Experimental and finite element model were investigated into aluminum alloy 2024-O sheet aircraft component forming via rubber-diaphragm forming technology.•Anisotropic yield criterion with ductile fracture model for the aluminum alloy and the hyper-elasticity model for the rubber materials were implemented.•The rubber-diaphragm forming simulations were found to be in good agreement with the experimental results.•The influence of process/materials parameters, such as friction and ductile fracture modeling form on the flexible forming process was studied.
