Assessment of fatigue strength of welded steel joints at sub-zero temperatures based on the micro-structural support effect hypothesis ...
Obwohl bekannt ist, dass sich die Materialeigenschaften von Stahl und deren Schweißverbindungen mit sinkenden Temperaturen ändern, wurden die Ermüdungsfestigkeit bei Minusgraden bisher kaum erforscht und Bemessungskurven und -methoden für Raumtemperatur werden auch auf Minusgrade angewendet. Mittels...
