Stress intensity factors for complete circumferential surface cracks in thermally shocked pipes
Description
In the case of an emergency cooling of a reactor thermal stresses are generated in the pipes of the primary loop, which may be described conservatively as a thermal shock problem. In this paper complete interior circumferential surface cracks loaded by these thermal stresses are considered. By means of the weight function method stress intensity factors were calculated for this loading case. (orig.)
Abstract (German)
Bei einer Notkuehlung werden in den Primaerkreisrohren Waermespannungen erzeugt, die sich konservativ durch ein Thermoschockproblem beschreiben lassen. Die Waermespannungen werden hier als Belastung fuer vollstaendig umlaufende Oberflaechenumfangsrisse eingesetzt. Mit Hilfe der Gewichtsfunktionsmethode werden Spannungsintensitaetsfaktoren fuer diesen Lastfall berechnet. (orig.)Additional details
