Material Tensile Testing Explained

How can a specific material/metal be simulated accurately? The uniaxial tensile test is performed to collect data from actual steel samples, and the results are used in sheet metal stamping simulation to accurately model the hardening behavior of the steel being simulated.

StampingSimulation.com utilizes the services of ThyssenKrupp Laboratory Services, Detroit MI, USA to perform the standardized test and prepare the appropriate data.

The raw data from the tensile test is imported to AutoForm Incremental metal stampingsimulation software and used as the basis for the material properties being simulated. These properties determine how the material behaves during forming and ultimately, when the materialwill fail. StampingSimulation strongly recommends tensile testing at the lab for all metalstampingsimulation jobs, however, in some cases a matching library material may be selected when physical material samples are not available.

The tensile testing procedure is usually quoted with each stamping simulation job, when required, and lab results are available within 24 hours of receiving the material sample which means there is little delay to the final simulation results.
