Question

The strength coefficient (K) and the work hardening exponent (n) for a stainless steel were determined during the analysis of the data from a tensile test using a standard tensile specimen. The flow curve parameters for the stainless steel are K= 1250 MPa and n = 0.4. A compression test is performed on a specimen of the stainless steel. If the starting height and diameter of the specimen are 80 mm and 18 mm, respectively and the final height of the specimen is 60 mm, calculate the load that was applied to the specimen. Assume that the cross-section of the compression is uniform from top to bottom during the test.
