1. The rectangular plate shown in (a) is modelled by Student A using the 3-noded triangular element as shown in (b). The node labels of two typical elements (elements 1 and 2) are shown in (c). Student A wants to use Equation (41) of Lecture 7 to calculate the element stiffness matrix. Student A has asked for comments from Student B, who says that the FEM model has several shortcomings. However, Student A insists that his FEM model is very good. (a) In your opinion, are there shortcomings of the FEM model proposed by Student A? If yes, then please list the shortcomings one by one and explain each.
