Multiparametrical model of crack propagation in structural elements and specimens for FEM calculations

EDN: RLYVXW

Abstract

   An important aspect of Russian national interest protection in Arctic is the application of shipbuilding steels ensuring no cases of brittle fracture at low service temperatures. Cold resistance of steels is verified by special mechanical tests, their required results should have a calculated substantiation. This paper considers finite element method (FEM) simulation of structural members made of steel plate and specimens and gives a description of suggested conditions of concurring brittle and ductile fracture. Local fracture conditions connect a brittle fracture event with an attainment of a critical first principal stress to stress intensity ratio while a ductile one with an accumulated plastic tear and shear strain. Their simultaneous application allows the simulation of fracture appearance and quantitatively assessment of the interrelation of different parameters, e. g. in case of drop weight tear test, the shear portion and impact energy, as well as the fracture toughness needed to arrest a crack in a typical structural element. The above technique gives an opportunity of the required ductile-to-brittle transition temperatures substantiation.
