Introduction,ng models. According to the kind ofmodelling, a distinction is made in this book between multibody systems, finite element systems, and continuous systems. All of these mechanical models lead from their equations of motion to state equations, which can be solved numerically by consistent methods.

Finite Element Systems,in the stiffness matrix of a single finite element. The nodes of the elements are linked by means of holonomic constraints, and external forces and torques can also act upon the nodes. Many details concerning the finite element method can be found e.g. in Wriggers , Bathe , or Zienkiewicz and Taylor .

James F. Albrecht,Garth den HeyerConstrained systems are thus assigned to free systems in accordance with themethod of sections. Starting from the kinetics of the point, we will proceed to the kinetics of the rigid body and of a continuum. The basic equations of kinetics, the Newton and Euler equations, constitute, together with th

Neil Dubord,Catherine Parent,Rick Parents. In addition, other arbitrary external forces and torques can also influence the system. Amass point system is a special case of a multibody system. For example, we can represent a multibody system as amass point system if all rotational velocities and all internal and external torques vanish with

James F. Albrecht,Garth den Heyerated modelling ofinfinitesimal volume elements, the elastic continuum has infinitely many degrees of freedom, while its motions are determined locally by partial differential equations. First the local Cauchy equations of motion for a free continuum and for the elastic beam as a continuum with inter
