LIMIT STATE ANALYSIS OF A PRESSURE VESSEL

Posuda pod tlakom konstruirana je za rad pri sobnim temperaturama i određenom radnom tlaku. U radu se analiziraju granična stanja takve posude po tlakom, radi potencijalne prenamjene posude. U prvome redu analizira se pojava plastičnih deformacija pri sobnoj temperaturi, a zatim i puzanje na povišenim temperaturama. Provodi se i globalna analiza čvrstoće te lokalna analiza čvrstoće.A pressure vessel is designed for operation at room temperature and given design pressure. The paper analyzes the limit states of such a pressure vessel for a possible change of operational conditions. In the first case, plastic deformation of the pressure vessel is analyzed, while the second case deals with creep at elevated temperatures. Both global and local stress analyses were carried out
