A 3-m by 1-m by 2-m parallelepiped is deformed by movement of corner A to A’ (2.9995, 1.0003, 1.9994), as shown in Fig. P2.19. Assuming that the displacement field is given by Eqs. (2.22), calculate at point A (a) the strain components and ascertain whether this strain distribution is possible; (b) the normal strain in the direction of line AB; and (c) the shearing strain for the perpendicular lines AB and AC.
