Dynamic Instability of Laminates Subjected to Temperature Field
Publication: Journal of Engineering Mechanics
Volume 124, Issue 10
Abstract
The dynamic instability of laminated composite plates subjected to thermal load is investigated. The formulation is based on first-order shear deformation theory and Lagrange's equation of motion. The non-linearity due to moderately large deformation of the laminates is considered using von Karaman's assumption. The eigenvalue type of solution for the nonlinear problem is evaluated through an iterative procedure. The boundaries of the primary instability region are presented using the relationship between the excitation frequency of the temperature load and the amplitude of the dynamic load for various levels of amplitude of vibrations of the laminates.
