Changes in the plasticity characteristics in air and in a hydrogenating environment of prestressing steel wires due to cold drawing process are investigated on the basis of slow strain rate tests on smooth specimens. The ...

The paper presents conclusions drawn from studies related to old steel structures, especially those erected on the turn of the 19th century. The objects of interest of the authors were Wroclaw Pomorskie Bridges: the Central ...

The evolution of silica optical fibers strength aged in cetyltrimethylammonium chloride solution (CTAC) are investigated. The mechanical behaviour of silica coated and naked fibers in contact with CTAC solution at different ...

The paper presents a review of the multiaxial fatigue criteria including a ratio of normal and shear stresses. The paper also contains fatigue characteristics for bending and torsion of some selected constructional materials. ...

The paper presents the analysis of the stress-and-strain state of a contacting couple consisting of two isotropic semi-infinite solids one of which has a small surface recess. Based on the classical criteria of fracture, ...

Cold drawing process is widely used for strengthening of wires made from pearlitic steels for reinforsed concrete structures. Then the steels undergo plastic deformation and the amount of defects rises. It could worsen ...

White metals (SnPbCuSb) are widely used as journal bearing materials for tin and lead based alloys. In this study, tribological and mechanical properties of these journal bearings manufactured from Sn based SnPbCuSb, pure ...
