For the linear strain tetrahedral element shown in Figure P11–8, (a) express the displacement fields
For the straight force tetrahedral atom shown in Figure P11–8, (a) direct the dismemberment fields u, v, and w in the x, y and z directions, respectively. Hint: There are 10 nodes each delay three translational degrees of insubservience, ui, vi, and wi. Also contemplate at the straight force triangle dedicated by Eq. (8.1.2) or the expansion of Eqs. (11.2.2).
