Dual Limit Analysis Problems With Discontinuity of Displacement Velocities
|Published in:||Journal of Civil Engineering and Management, June 1995, n. 2, v. 1|
The general dual mathematical models (static and kinematic formulations) of the limit load and rigidplastic body parameters optimization problems are formed on the basis of extremal energy principles and theory of duality. Yield conditions are controlled not only in volume of finite elements, but also at the surfaces between elements. Therefore the possible discontinuity of displacement velocities and velocity energy dissipation between the elements are evaluated.
