| Abstract Scope |
Constitutive laws for hot forming typically consider the effects of strain, strain rate and temperature. Their parameter identification requires experiments performed on wide ranges of these three factors. Usually, specialized equipment is utilized to ensure uniform strain, strain rate and temperature. Alternatively, parameter databases provide parameter sets for various materials and constitutive laws at a low cost. This work explores the potential of using compression experiments on industrial presses for parameter identification of such constitutive models, in order to balance the cost and accuracy of these two existing alternatives. The results are compared to reference results produced on specialized large temperature / strain rate compression equipment. Two materials are used to prove the usefulness of the proposed methodology. |
