A variational principle in torsion problems of composite rods
A modified Lagrangian variational principle is applied to problems which involve bodies composed of homogeneous parts, i.e., the density function of strain energy is discontinuous. A general case of Saint-Venant's free torsion problem is considered as an example. The location of the torsion cen...

| Summary: | A modified Lagrangian variational principle is applied to problems which involve bodies composed of homogeneous parts, i.e., the density function of strain energy is discontinuous. A general case of Saint-Venant's free torsion problem is considered as an example. The location of the torsion center is given as the solution of an extremum problem. |
