20.500.12556/RUL-103041 Napetostno stanje v nezvezno temperaturno obremenjeni okrogli cevi Stress state in non-uniformly temperature loaded circular tube Obravnavali smo problem temperaturnih napetosti v homogeni, izotropni debelostenski cevi. Za izpeljavo enačb smo uporabili upogibno teorijo. Upoštevali smo dejansko debelino cevi in nezvezno porazdelitev temperature na notranjem robu cevi. Temperaturo na zunanjem robu cevi smo po celotnem obodu upoštevali enako in konstanto. Pri izpeljavi temperaturne porazdelitve po cevi smo uporabili metodo kompleksnih spremenljivk. Na osnovi znane temperaturne porazdelitve smo z upogibno teorijo izpeljali enačbo za določitev temperaturnih napetosti. Rezultati enačbe se precej dobro ujemajo z rezultati, ki so jih objavili drugi raziskovalci. We discussed the problem of thermal stress in homogeneous, isotropic thick-walled tube. The banding theory was used to derive the equations. We took into account the actual thickness of the tube and the non-uniform temperature distribution on the inner edge of the tube. The temperature on the outer edge of the tube throughout the perimeter was considered constant. The temperature distribution in the tube was derived by using complex variable method. Based on known temperature distribution we used banding theory to derive the thermal stress equation in the tube. The results of our equation match quite well with the results published by other researchers. temperaturna porazdelitev deformacije radij ukrivljenosti temperaturne napetosti temperature distribution strain radius of curvature thermal stress true false false [M.
