Torsional capacity of lean duplex stainless steel semi elliptical hollow section members a finite element study

Abstract

Lean Duplex Stainless Steel LDSS offers the combined benefit of low initial cost due to low nickel content of 1 5 and relatively superior material property high strength good corrosion resistance good weldability fracture toughness etc and making LDSS as one of the promising grades of stainless steel family It may be mentioned that lean duplex stainless steel has been included for the first time in EN 1993 1 4 2006 via a recent amendment A1 2015 Adequate understanding of the...
