Aufbau einphasiger fester Stoffemechanics of systems of rigid bodies, has appeared and now it is succesfully developing. This is especially valid for the theory of rotation of a rigid body on a string which is a limit case for the motion of a couple of bodies.

r orbit. The structure is modeled as a viscoelastic solid with high stiffness; the characteristic decay time of its free elastic oscillations is assumed to be small compared to orbital period of the center of mass. Linear elasticity is used, with frictional dissipation being introduced through RayleLAIR 发表于 2025-3-27 09:06:48
