(a) By referring to the material matrix for plane strain condition, explain briefly the limitation of (V) constant strain triangle (CST) element. question not clear. (b) A CST element has the nodal coordinates (0, 0), (75, -50), and (75, 50) which are measured in mm for the first, second, and third nodes, respectively. The element is to be considered in plane stress with a thickness of 10 mm and is made of a material with properties E = 200 GPa and v = 0.3. Upon loading the model the nodal displacements were found to be: {91 92 93 94 95 96) =(-0.138 0.209 -0.080 0.155 0.031 0.141) mun Determine: (ii) the element stiffness matrix the element stresses (a) By referring to the material matrix for plane strain condition, explain briefly the limitation of (V) constant strain triangle (CST) element. question not clear.
