Finite Element Analysis Using MATLAB Toolbox
mae.ufl.edustiffness matrix Kin the location that is specified in the first row of Edofarray. The result is returned to the global stiffness matrix Kso that the matrix Kcontains the accumulated data from all elements. The global stiffness matrix Kin (P.4) is singular because there is a rigid body motion in the system.

2D Triangular Elements
www.unm.eduAt this point, we are about half way to developing the stiffness matrix for the triangular mesh. We can use equation 4.13 to rewrite equation 4.2 so that U T tdA = ∫A εσ 2 1 (4.2) becomes U T D tdA = ∫A ε ε 2 1 (4.15) We have eliminated the stress term in the equation. We will go on from here to eliminate the strain term and develop the ...
