A The Four Nodes Of The Isoparametric Element As Shown In Fig 6 Have The Detailed Coordinates Of Node 1 20 20 Nod 1 (31.55 KiB) Viewed 18 times
(a) The four nodes of the isoparametric element, as shown in Fig.6, have the detailed coordinates of Node 1 (20,20), Node 2 (40,20), Node 3 (40, 40), and Node 4 (20, 50). The detailed stresses of the four nodes are 300, 350, 400, 450 MPa, respectively. Inside the element, there is a Point P with the local coordinate of (0.35, 0.35). Determine the global coordinate X and Y of Point P and its stress. (8 marks) 3.682.
