(b) assumptions: linear, elastic, isotropic, homogeneous 2 2 2 1 2 1 1 1 2 1 2 1 kk ij ij kk ii ij ij kk ij ij ij ij ij E E W E E E E W 2. For a linearly elastic isotropic material starting from kk ij ij ij 2 (4.1) show that E ij 1 ij ij kk (4.2) To this end, we first determine kk in terms of kk from (4.1) by setting k j i to yield 2 3 3 2 kk kk kk kk kk kk 2 3 1 (4.3) Now by solving (4.1) for ij and substituting from (4.3), we obtain the inverse form of the and substituting from (4....
