Experimental study of ferritic stainless steel bolted T-stubs under monotonic loading

Numerical modelling of stainless steel bolted T-stubs in tension

“…Additional studies on stainless steel connections were reported by Wang et al [34], Bu et al [35], Song et al [36], Gao et al [37], Yuan et al [38] and Yapici et al [39][40][41] conducted experimental and numerical studies on the behaviour of stainless steel connections and reported similar conclusions.…”

Numerical simulation and design of ferritic stainless steel bolted T-stubs in tension

“…The studies in the literature focused primarily on austenitic and duplex stainless steel grades, while the structural performance of ferritic stainless steel connections has not been studied to date. In order to fill this gap in the literature, the ultimate behaviour of ferritic stainless steel bolted T-stubs under tension has been studied by the authors and reported as a companion paper in reference [35]. According to recent experimental studies, the ferritic stainless steel T-stubs [35] display a different behaviour compared to their austenitic and duplex counterparts [33].…”

“…In the companion paper [35], 17 experimental tests on ferritic stainless steel T-stubs in tension were reported, thus augmenting the limited available data pool [20,33] with the first ever ferritic stainless steel T-stub results ever to be reported. In this paper, recommendations for the numerical modelling of ferritic stainless steel T-stubs are provided.…”

“…In this paper, recommendations for the numerical modelling of ferritic stainless steel T-stubs are provided. Following the observations on the pronounced anisotropy of ferritic stainless steel [35], the effect of material anisotropy is discussed in detail, whilst a comprehensive discussion on mesh size and analysis procedures is also included. Furthermore, the stress distribution developed on the flange to web junction at various load levels is inspected and the validity of current design assumptions regarding the development of stresses and the applicability of plastic design procedures is assessed.…”
