FREE VIBRATION ANALYSIS FOR PLATES USING GENERALIZED CONFORMING THICK/THIN TRIANGULAR ELEMENT
厚薄板通用三角形广义协调元TCGC-T9的固有振动分析

The free vibration property of the generalized conforming thick/thin element TCGC-T9 is studied in this paper.The first five natural frequencies with different plate thickness are obtained using the sub-space iteration method.By comparing the results with those obtained by ABAQUS and the theoretical solution,it can be concluded that the TCGC-T9 element enjoys the following advantages:good convergence,high numerical stability and excellent applicability (valid for both thick or thin plates) in analyzing free vibration of plate.
