A 3-noded triangular element (plate) is shown below. The nodal displacements (in metres) of the element are Young's modulus E=200GPa Poisson's ratio v=0.3 Plate thickness t=5mm Determine 1) The displacements at point P whose coordinates are (0.2,0.4) (in metres) (10 marks) 2) [B] matrix for the element (10 marks) A 3-noded triangular element (plate) is shown below.
