The stiffness and compliance tensor coefficients for lead and tungsten, which are both cubic crystals, are shown below: Symbol $11 512 544 C11 C12 C44 Units Pb 10-11 m/N 9.3 10-11 m/N 10-11 m/N 10 N/m 10 N/m 10 N/m? -4.24 6.9 47 40 14.4 W 0.26 -0.073 0.66 500 200 140 (a) Construct the appropriate stiffness or compliance matrices for lead and tungsten that you need in order to calculate strain from stress. (b) Calculate the strain tensors for lead and tungsten under the following stress state: 011 10 MPa and 22 = 20 MPa The stiffness and compliance tensor coefficients for lead and tungsten, which are both cubic crystals, are shown below: Symbol $11 512 544 C11 C12 C44 Units Pb 10-11 m/N 9.3 10-11 m/N 10-11 m/N 10 N/m 10 N/m 10 N/m? -4.24 6.9 47 40 14.4 W 0.26 -0.073 0.66 500 200 140 (a) Construct the appropriate stiffness or compliance matrices for lead and tungsten that you need in order to calculate strain from stress.
