2.1 – MATERIAL MODEL For each of the questions below, choose the correct answer. Name Email 1. In isotropic material the stress-strain equations are independent of location of the point. True False None 2. In non-homogenous material the material constants are functions of coordinates. True False None 3. 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 None 4. There are three independent material constant relating stresses and strains in isotropic material True False None 5. The matrix relating stresses and strains for orthotropic material changes with coordinate transformation. True False None 6. Principal directions for stress and strain are same for orthotropic material. True False None 7. The Generalized Hooke’s law is valid for any orthogonal coordinate system for isotropic material. True False None 8. The Generalized Hooke’s law is valid for non-homogenous, isotropic material. True False None 9. Material volume does not change during deformation. True False None 10. The maximum shear stress depends upon whether the point is in plane stress or plane strain. True False None Do you have any comments or suggestions?
