1. Failure Modeling (10 points) - Von Mises Criteria You have a state of strain defined by the values below, note that the shear values are the actual shear strains and NOT divided by 2 for transformation. If Young's modulus is 70 GPA, Poisson ratio is 0.3 and K E/(3(1-2), G=E/(2(1+)), λ= vE/((1+v)(1-2)), calculate a. (5pts) the stress field in MPa, don't forget that the strains are in microstrains. b. (5pts) the safety factor for a Von Mises criteria if the yield stress is 500 MPa. [100 500 4001 Strain is: 500 200 L400 200 200 μstrains 300] a. Stress (MPa) is: b. Safety Factor =
