Reference no: EM13887025

Two points on a stress-strain curve for a material are σ = 278 MPa at ε = 0.08 and σ = 322 MPa at ε = 0.16.

A. Find K and n in the power-law approximation and predict σ at ε = 0.20.

B. For the approximation σ = K (εo + ε)n (Equation (5.4)) with εo = 0.01, ?nd K and n and predict σ at ε = 0.20.
