Consider a hot working operation where there is no work hardening but the flow stress is sensitive to strain rate. Calculate the maximum strain rate that can be used in the deformation if the flow stress cannot exceed 200 MPa. Assume a strain rate sensitivity exponent is 0.1 and the strength constant is 175 MPa. There is no effect of friction with the tooling
