For a LEHI material, the principal plane stresses and associated strains in a plane at a point are o,=36 ksi, 02=16 ksi, ɛ1=1.02 x 103, and E2=0.18 x 103. Determine the Young's modulus and Poisson ratio of the material. Hint: use the equations for principal stress for 2D plane stress for LEHI, and consider 02/01.
