  Stal 34HNM i 26H2MF, poddana różnym obróbkom cieplnym wykazała skłonność do korozji naprężeniowej przy pomiarach ze stałą szybkością rozciągania (10-6s-1) i pomiarach niskocyklowego zmęczenia, wykonanych w paliwie kotłowym. Mechanizm korozji naprężeniowej określono jako kruchość wodorowa, co zostało potwierdzone w pomiarach pochłaniania wodoru z tych środowisk. Jako możliwe źródła wnikania wodoru do stali omówiono procesy korozyjne,...

  The development of laser welding technology has enabled the mass production of thin-walled structures, including steel sandwich panels. The technology of joining plating panels with stiffeners by welding allows us to create joints with a specific geometry and material properties. In comparison with other types of joints, laser welds are characterized by their specific behaviour under cyclic load and, as a consequence, a different...

  This work deals with dimensioning of wireless mesh networks (WMN) composed of FSO (free space optics) links. Although FSO links realize broadband transmission at low cost, their drawback is sensitivity to adverse weather conditions causing transmission degradation on multiple links. Hence, designing such FSO networks requires an optimization model to find the cheapest configuration of link capacities that will be able to carry...

  Within the strain gradient elasticity we discuss the dynamic boundary conditions taking into account surface stresses described by the Steigmann–Ogden model. The variational approach is applied with the use of the least action functional. The functional is represented as a sum of surface and volume integrals. The surface strain and kinetic energy densities are introduced. The Toupin–Mindlin formulation of the strain gradient elasticity...
