Determining the true strain in the larger area

Assignment Help Mechanical Engineering
Reference no: EM13887030

Consider a tensile specimen made from a material that obeys the power hardening law with K = 400 MPa and n = 0.20.  Assume K is not sensitive to strain rate. One part of the gauge section has an initial cross-sectional area that is 0.99 times that of the rest of the gauge section. What will be the true strain in the larger area after the smaller area necks and reduces to 50% of its original area?
