MCE 561 Computational Methods in Solid Mechanics Homework Assignment 5 Due March 9, 2011 1. For the differential equation f u = 2 , using the following linear triangular element with the node numbering as shown, determine: a.) the three interpolation functions b.) the element matrices [ K ] and { f } Partial Ans. ... , 8 / 3 , 8 / 5 12 11 = = K K 2. Consider the rectangular element shown in Figure 8.2.12 (in text), for the differential equation f u = 2 . Explicitly verify the first row of the stiffness matrix given by equation (8.2.54). Use the interpolation functions given in terms of local coordinates, equations (8.2.32a), to do the
