Question

A tensile test is performed on a metal specimen, and it is found that a true plastic strain of 0.28 is produced when a true stress of 457 MPa is applied Assume the material to be a power-law hardening type, with power-law coefficient K equal to 900 MPa. The true strain that results from the application of a true stress of 664 MPa (rounded off to two decimal places) is​
