Commercial manganin stress gauges are used in planar impact experiments to determine spall strengths of variously heat‐treated 2024A1 specimens. A one‐dimensional Lagrangian code is used to find the best fit of calculated versus experimental stress histories by varying the spall strength in the code and using a simple threshold criterion. We found values in the range of 1.2–1.75 GPa for spall strengths of the differently treated specimens. These values are in good agreement with published data… CONTINUE READING
