Material A has a modulus of elasticity between Materials B and C, where the value of Material B is the highest and Material D is the lowest. Materials A and B do not undergo plastic deformation with the same strain value. Material B has the same strength as Material C, but higher than Material A. The strength of Material A is the same as that of Material D. Materials C and D experience the same strain with considerable plastic deformation. a. Draw the stress strain curves of the 4 Materials in one axis b. If you are asked to select a material according to the following criteria (state and explain why): i. Highest toughness: ii. Highest stiffness Supreme power iv. Highest tenacity If an application requires a material with low stiffness and high ductility, which material will you choose?
