A control volume based formulation of the discrete Kirchoff triangular thin plate bending element [PDF]

, 2009
A control volume method is presented for predicting the displacement and rotation of thin transversely loaded flat plates. The new procedure uses discrete Kirchoff triangle (DKT) elements but introduces a dual mesh of interconnected control volumes (CVs)
