d'Alembert's principle

(General Physics) physics the principle that for a moving body the external forces are in equilibrium with the inertial forces; a generalization of Newton's third law of motion

[C18: named after Jean Le Rond d'Alembert (1717–83), French mathematician, physicist, and rationalist philosopher]

The principle of virtual work for plane strain condition describes the structural model which forms the differential algebraic equation (DAE) systemalong with heat equation which describes the heat transfer phenomena.

2D MODEL OF HUMAN'S LEG SHAPED ROBOTIC LEGBASED ON POLYIMIDE FILLED V-GROOVE JOINTS

The principle of virtual work and various energy methods calculate the displacement of beams and trusses and the effects of temperature gradients in beams while the finite element method establishes the stiffness matrix for each element in a continuum structure.
