2.10.14 Plate Element

For the rectangular bending element shown in Figure 2.90 with three degrees of freedom (one deflection and two rotations) at each node the displacement function can be chosen as a polynomial with 12 undetermined constants as

{/ } = w = A1 + A2X + A3y + A4X2 + A5xy + A6y2 + A7X3

The displacement parameter vector is defined as

{D*} = {w;, 0xi, 0yi| Wj, 0xj, 0yj| w*, 0xi, 0yi | w/, , $y/}

where

0 0
