Behaviors of a single crack in multiple bolted joints

摘要: This paper examines the pin load ratios and stress intensity factors (SIFs) of a single crack in multiple bolted joints by using finite element analyses. Cubic-spline contact elements rigid links were used to model surface between bolt pin. The least-squares method was determine SIFs. results indicate that cracked hole can still sustain major part original loading at uncracked condition. first sustains largest mode-I SIF, which are reduced little for propagation. critical condition cannot be arrangement more pins plate. In this paper, two simple formulae also investigated fit SIFs bolted-joints problems.
