Abstract [en]

Local limit load solutions for plates containing semi-elliptical surface cracks subjected to pure membrane loading cases, pure bending loading cases and combinations of the two are determined using non-linear finite element analysis. Both loading cases that open the crack and loading cases that close the crack are considered. The study covers both shallow and deep cracks with different aspect ratios. Results from the finite element simulations are fitted to an analytical expression. The local limit load solutions from this work are compared with global and local limit load solutions from previous work. Furthermore, infinite cracks and the effect of crack-face contact are investigated.

Abstract [sv]

Lokala gränslastlösningar för plana plåtar innehållande semi-elliptiska ytsprickor som belastas med en membranlast eller en böjlast eller en kombination av båda är presenterade. Lastfall som både öppnar och stänger en spricka beaktas. Lösningarna är framtagna med hjälp av icke-linjär FE-analys. Arbetet omfattar både grunda och djupa sprickor med olika längd-djupförhållanden. Resultaten från FEanalyserna är kurvanpassade till ett analytiskt uttryck. De lokala gränslastlösningarna jämförs sedan med tidigare framtagna globala och lokala gränslastlösningar. Dessutom undersöks plana plåtar med oändliga sprickor och inverkan av kontakten som uppstår mellan sprickytorna.
