Hace 4 días · The crack length vs. number of cycles and the calculated stress intensity factor range vs. fatigue crack growth rate values (the kinetic diagrams) for S960M GMAW welded joints in ... Manurung YHP (2020) Welded high strength low alloy steel influence on fatigue crack propagation using LEFM: a practical and thematic review. Struct ...
Hace 1 día · Functional fatigue of the two types of electrical steel results in increased power losses due to the specimens exhibiting pronounced ratcheting. Abstract The mechanical fatigue and functional fatigue of a non-oriented electrical steel (NOES) and a grain-oriented electrical steel (GOES) are investigated under stress-control in the high cycle fatigue regime.
Hace 3 días · An SHS-CFSHS X-joint is fabricated by welding two square hollow section (SHS) braces to a concrete-filled square hollow section (CFSHS) chord. In this paper, the stress concentration factors (SCFs ...
Hace 3 días · Small-hole structures, such as the millions of fastener holes found on aircraft, are typical stress-concentration structures prone to fatigue failure. To further improve the strengthening process of this small-hole structure, we make up for the limitations of laser shock processing (LSP) of small holes by combining it with the ultrasonic extrusion strengthening (UES) process to form a new ...
Hace 2 días · The Engel Maier correction formula not only reduces the number of model parameters but also simplifies its structure. By incorporating temperature-influencing factors, the results obtained through this formula tend to be relatively accurate. Consequently, it finds widespread application in calculating the thermal fatigue life of solder joints.
Hace 1 día · Abstract. Residual tensile stresses and microstructural heterogeneity in welded joints are primary factors that degrade fatigue performance. Addressing this issue, this paper leverages the precise control and customizability of Laser Shock Peening (LSP) to propose a technique called Laser Non-Uniform Shock Peening (LNUSP) for welded joints.
