(4) (3) F (1) (2) L S H
. A thin plate is composed of four CST elements, as shown in
the figure below. The plate is subjected to a uniform tensile traction s
acting on the right edge and a concentrated force F at the center. Use
the following values: E = 105 GPa, ν = 0.3, t = 5 mm, L = 400 mm,
H = 400 mm, s = 50 MPa, and F = 150 kN.
(a) Compute all the nodal displacements.
(b) For each element, compute the element stress components σxx, σyy,
and τxy.
(c) For each element, compute the element planar principal normal stresses
σ1
′ and σ2
′.
(d) For each element, compute the Von Mises and Tresca effective stresses.
Please help solve using only FEM( Finite Element Method) and the values given, very urgent. Thank you.
