On dual approach to piecewise-linear elasto-plasticity. Part II: Discrete models.
A. BORKOWSKI
 
The second part of the paper presents finite-dimensional models of linear elastic, elastic-strain hardening, elastic-perfectly plastic
and rigid-perfectly plastic structures. These models can be seen as a result of discretisation procedure applied to the models of solids derived in the Part I. The implications of sub-dividing degrees of freedom into those with prescribed external forces and those with given displacements are discussed. It is pointed out that the dual energy principles given in this part of the paper can serve as a direct basis for numerical computations.
 
Keywords:
imposed displacements, energy principles, mathematical programming
