The components of the displacement vector (u) at a point (X, X2, X3), with respect to (x, x2, x3) coordinate system, are given as: = = a^(XX + XX) + aXXX U = ba (X2X3) + aXX3 1 U3 = = axxx Find: a. The components of the displacement gradient tensor (Vu). b. The components of the linear strain tensor (E) at the point (P): (3,3,1) and (b = 12) c. The value of (a) if a unit elongation at (P) with respect to the direction n=- [101] 1 2 is given as (Enn = 1.5 x 10-8) d. The shear strain at (P) with respect to the directions 1 3 k = m = [1 1 1], =110
