Adisplacement field in a body is given by u =c{x^2 +10) v = 2cyz w = c(- xy + z^2) where c=10^-4. the displacements in x, y and z directions are u, v and w respectively. determine the state of strain at the coordinate point (0, 2, 1) using small strain definitions. what is the normal strain along the line with direction (1/squareroot 3, 1/squareroot 3, 1/squareroot 3) at point (0, 2, 1) calculate the volumetric (dilatational) and distortional (deviatoric) components of the total strain. what do they represent?
