This article describes the role of the finite element method (FEM) in the study of span structures. The choice of software for the FEM implementation has been rationalized. The use of the modern package of finite element analysis Femap with NX Nastran in order to model and calculate reinforced concrete bridge span structures has been reviewed. The sequence for reinforced concrete analysis has been...
W pracy przedstawiono trójwymiarowy węzeł tarcia do badań tribologicznych oraz rozkład naprężeń i odkształceń w skojarzeniu ślizgowym warstwy duplex powstałej w wyniku obróbki cieplno-chemicznej. Badania przeprowadzono dla ruchu posuwisto-zwrotnego w warunkach tarcia technicznie suchego przy średniej prędkości ślizgania 0,2 m/s oraz obciążeniu 32 N. Przedstawione wyniki badań MES stanowią ważną informację,...
