Abstract

Air-springs are characterized by strongly anisotropic material behavior and can simultaneously undergo large elastic deformations. This attribute involves an appropriate constitutive model for an adequate numerical simulation of these components' complex response. The present paper discusses the manufacturing process of an air-spring and deals with the use of anisotropic-based hyperelastic constitutive model in the context of thin membranes inflation. In order to investigate the capability of the proposed model, some finite element analysis were conducted by using ANSYS 15.0. The proposed model shows a good predictive ability and exhibits a good agreement when compared to the experimental work of the present paper
