Determination of strain rate dependence at intermediate strain rates using acceleration information [PDF]
International Journal of Impact Engineering, 2023 Precise stress-strain characteristics of materials for intermediate strain rates need to be utilized for analyzing various events in industry such as metal forging, sheet metal forming in manufacturing processes and automotive crash tests. However, the accurate evaluation of the load is not easy at intermediate or high strain rates, owing to the ...
