On the inverse identification of sheet metal constitutive parameters using a virtual experiment and the Arcan test

In the modern industry, modelling and simulation are crucial phases of product development. Simulation tools in solid mechanics use constitutive models and their parameters to describe the behaviour of materials. Classically, each homogeneous experimental test represents a single stress/strain state. Therefore, an extensive experimental campaign is typically required to fully characterise the material behaviour. Nowadays, with the use of heterogeneous test configurations and full-field measurements, it is possible to measure a combination of multiple stress/strain states, therefore, being able to identify several parameters from a single test with reduced cost and time.
