On the variational principles in the mechanics of classical continua (Q1109601)

In this paper, along with the well established lines of the analytical mechanics, we aim to show an autonomous formulation of the fundamental principle of Lagrange-d'Alembert and of the subsequent Hamilton principle in classical mechanics of deformable continua in the sense that the afore-mentioned principles do not turn out to be a reformulation of the well known undefined equations of motion.
