Modelling of Piezothermoelastic Beam with Fractional Order Derivative

Curved and Layered Structures, 2016
This paper deals with the study of transverse vibrations in piezothermoelastic beam resonators with fractional order derivative. The fractional order theory of thermoelasticity developed by Sherief et al. [1] has been used to study the problem.

Generalized completely integrable systems [PDF]

Theoretical and Applied Mechanics
Dynamical systems more general than Hamiltonian systems are considered. The role of the Hamiltonian function is played by a 1-form (not necessarily closed) on a symplectic phase space.
