5. Find the toughness for a metal that experiences both elastic and plastic deformation. Assuming o=&E for elastic deformation, that the modulus of elasticity is 172 GPa, and the elastic deformation terminates at a strain of 0.01. For plastic deformation assume the relationship 07 - KETE values for K and n are 6900 MPa and 0.30, respectively. Note that plastic deformation occurs between values of 0.01 and 0.75, at which point fracture occurs.
