Abstract:
In this paper the finite element method approach is presented in order to determine the effective stress redistribution and deformation in the bolted beam end-plate connection assembled with high tensile bolts. Connection is represented via HEA profile with both end-plates, bolted to the I-shape short cantilevers welded to the supporting columns. [..]

Abstract:
The need for decision-making is related to management, constituting the substance thereof. Management means the wilful, purposeful influencing of a certain process, phenomenon or situation in order to achieve the required outcome or objective.Therefore, we make decisions in the case of a deviation from the required status and if the achievement of the objective is at risk, or when we get into a situation when the objective can be achieved in several different ways.

Abstract:
Monitoring the mechanical properties changes is very important to assure structural integrity of NPP components, especially within the context of their operational life extension. Determination of current mechanical properties of several structural materials of NPP components, especially reactor internals, is not possible using the standard testing methods, in connection with the material volume necessary for the testing.
