(b) The formula for the elasto-plastic tangent is on the formula sheet [{fo }{f.o) [De [Dep] = [De] | [1] [1-[88]] {f.o}T [De] {fo } we have [De] from part (a) so the students just need to calculate the derivative of the yield function with respect to stress, {f} {f}={10-1}. Looking at different components of [Dep] (all in GPa) 1 0 -1 270 135 135 135 0 - 135
