Projection Approach

This paper proposes a numerical scheme to approximate the solution of (vectorial) limit load problems. The method makes use of a strictly convex perturbation of the problem, which corresponds to a projection of the deformation field under bounded deformation and incompressibility constraints. The discretized formulation of this perturbation converges to the solution of the original landslide problem when the amplitude of the perturbation tends to zero. The projection is computed numerically with a multi-step gradient descent on the dual formulation of the problem.

Window sill of brick walls is one of the most critical places in a connection of two envelope types objectively. If there are the transparent and opaque parts present together, the connection is much more complicated. Different behavior of the construction materials in dynamic boundary conditions causes deformations of thermal field of the window sill detail. Numerical thermal field analysis verified by the experimental measurement in experimental outdoor chambers is used for recognize the real heat-air-moisture behavior in the various constructions.

Casing Pipe

The paper presents the results of the expert works in the area of diagnostics, repair, and reconstruction of the steel pipelines of the transit gas pipeline (TP) on Slovak territory. One part of our work included dynamic measurements of a steel casing pipe located under the railway. This pipeline was damaged by corrosion and it was necessary to evaluate its safety.
