Mechanical Engineering

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