Purpose: The purpose of the current research is to quantify the impact of notch parameters viz. width, depth and central angle (perimeter length) on the fatigue life of UNS S32760 grade of super duplex stainless steel. Design/ Methodology/ Approach: Finite element analysis approach is implemented by using the popular software package ANSYS 18.1 and the experimental runs are selected as per the requirements of Taguchi L9 orthogonal array. TOPSIS approach is used along with Taguchi method to know about the impact of notch parameters and arrive at the optimal condition. Findings: It is quantitatively established that notch depth is the most critical parameter and it affects the fatigue life to a greater extent (63.4%) when compared to other factors viz. notch width (10.6%) and central angle (7.31%).

Structural stainless steel design guidelines should appropriately recognise its characteristic beneficial properties such as material nonlinearity and significant strain hardening. The Continuous Strength Method (CSM) exploits those through a strain based approach for both stocky and slender cross-sections. In this paper, a new design method is proposed that combines the CSM with Perry type buckling curves. Numerical models were developed to investigate effects of various parameters on column strength and to develop full column curves. It was observed that material nonlinearity significantly influence column strengths, and hence, different column curves were developed for a total of 20 material property combinations by calibrating imperfection factor and limiting slenderness ratio for each set. Proposed method includes the strain hardening benefits for stocky section, and abolished the necessity of calculating effective cross-sectional properties for slender sections. Performance of the proposed technique is compared against those obtained by the Eurocode EN1993-1-4.

Steel, compared to iron is an alloy of iron with commonly a few percent of carbon to enhance its strength and fracture resistance. The use of stainless steel in the design of structures remains a relevant discussion across different areas. In fact, the importance of structural steel in the glocal world has applications in virtually every sector. Also, aluminum steel has been used widely in residential applications, commercial buildings, and vehicular (automotive) designs. A close comparison of these three sheets of steel will give enlightenment about what brings them together and their applications for such characteristics they possess that seem alike. Many researchers argue about the possibility of their sustainability both in terms of cost, availability, fire resistance, and fabrication. Understanding their behaviors following their comparison will provide accurate answers to these propositions. This paper compares the stainless, structural, and aluminum steels in terms of usage, properties (chemical and mechanical), compares exclusively the structural and stainless steel design provisions, reviews recent research activities, and highlights the important developments.
