A High Precision Shear Flexible Triangular Element for Vibration of Composite Shells

Shock and Vibration, 2004
A high precision triangular shallow shell element is proposed and it is applied to free vibration analysis of composite and isotropic shells. The Mindlin's hypothesis is followed to include the effect of shear deformation.
