4.6 by using (c) and (d). 4.7 Determine the constitutive relations governing the material behavior of a point having the properties described below. Would the material be classified as anisotropic, orthotropic, or isotropic? (a) A point in the material has a state of stress given by the following: 011 = 10.8; 223.4; 33 = 3.0 012013023 = 0. (b) The material develops the corresponding strain components: 11 = 10 × 10 4; 822 = 2 × 10-4; 833 = 2 × 10-4; 812823831 = 0. = (c) When a state of stress of 11 = 10; 22 = 2; 033 = 2; 012023=031 = 0 is applied, the strain components are 11 = 10 x 10 4; 22 = 833 = 12 = 823 = 831 = 0. (d) When subjected to a shearing stress 12, 13, or 623 of 10, the material develops no strains except the corresponding shearing strain, with tensor component &12, 13, or 823 of 20 x 10-4
