3.1 Mechanical Properties of Materials For each of the questions below, choose the correct answer. Name Email 1. Ductile material can undergo large elastic but small plastic deformation. True False 2. Poisson’s ratio value is between half and one. True False 3. Material volume does not change during deformation. True False 4. A tough material has a large ultimate stress but small area under the stress-strain curve. True False 5. The stress-strain equations are independent of the orientation of the coordinate system in isotropic materials True False 6. The material constants are functions of coordinates in non-homogenous materials. True False 7. The most general anisotropic material needs 36 independent constants to relate the six independent stress components to the six independent and strain at a point. True False 8. There are three independent material constant relating stresses and strains in isotropic material True False 9. The Generalized Hooke’s law is valid for any orthogonal coordinate system for isotropic material. True False 10. The Generalized Hooke’s law is valid for non-homogenous, isotropic material.
