WebbConventional tensile testing is done at strain rates slow enough to be called “quasi-static.” These rates are several orders of magnitude slower than the deformation rates during stamping, which itself is several orders of magnitude slower than what is experienced during a crash event.

WebbAdvent of high Strain Rate superplasticity with the total elongation of more than 400 pct was confirmed by pulling the tensile specimens with an Initial Strain Rate of 2.0 × … WebbStraining rate is a specified rate of strain of the parallel section of the specimen. It is run in extension control. The specified straining rate converts into an equivalent crosshead … WebbIndeed, performing multi-axial experiments at high strain rates is not obvious. Prediction of the initiation of necking in the steel sheets subjected to multi-axial strain states is based on the Marciniak-Kuczynski model. The thus obtained forming limit diagrams show a non-negligible effect of the strain rate. For the DC04 material, the reduced ... hilton opinion survey
