1. Fatigue failure analysis of HSLA steel sheets holed by conventional and flow drilling processes
RESUMO O processo de furação por escoamento produz buchas para uniões removíveis que podem ser roscadas pelo processo de rosqueamento por conformação, reduzindo etapas da produção de componentes da indústria automobilística e em galpões da construção civil. Aços de alta resistência e baixa liga (ARBL) são empregados em variadas aplicações n

2. Enhancement the Fatigue Life of Floating Breakwater Mooring System Using Tuned Liquid Column Damper
Abstract Safety is a key design criterion for floating structures. A high rate of mooring accidents has been reported over the past decades. Preventing mooring line failure is a key design objective for floating breakwater systems. The mooring system comprises sets of mooring lines anchored to the seabed. These components are exposed to highly cyclic nonline

3. Effect of cold-working process on cyclic deformation of electrolytic copper
Abstract Cyclic softening and hardening processes are expressed by the change in the stress amplitude necessary to cause a given strain amplitude. Understanding the cyclic stress-strain behavior of materials is an important step in the complex study of their fatigue behavior. The potential differences between the defect structures of cold-formed materials ma

4. Fatigue failure analysis of HSLA steel sheets holed by conventional and flow drilling processes
ABSTRACT Flow drilling process produces bushes for removable joints that can be threaded by forming tapping process, reducing stages in production of components of automobile industry and in construction sheds. High strength and low alloy steels (HSLA) are employed on several applications in the processing industry. Benefits provided by these materials make

5. Multi-walled carbon nanotube reinforced polymer as a bonded repair for Al 2024-T3 fatigue crack growth
ABSTRACT The influence on multi walled carbon nanotubes (MWCNT, or simply CNT) as a reinforcement material in an epoxy resin in order to decrease the fatigue crack propagation rate in the 2024 T3 aeronautical Al alloy was studied. CT samples were pre-cracked in a resonant fatigue machine until a 4 mm pre-crack length. Four groups of samples were considered:

7. Correlation of Stress Concentration Factors for T-Welded Connections – Finite Element Simulations and Fatigue Behavior
Abstract The stress concentration factors (SCFs) in welded connections usually occur at zones with high stress levels. Stress concentrations reduce the fatigue behavior of welded connections in offshore structures and cracking can develop. By using the grinding technique, cracking can be eliminated. Stress concentration factors are defined as a ratio of maxi

8. Continuum Structural Layout in Consideration of the Balance of the Safety and the Properties of Structures
Abstract In the article, a new approach considering structural local failure for topology optimization of continuum structure is proposed. It aims at not only lowering the risk of local failure in the concerned structural regions, but also ensuring a good stiffness of the structure. The local failure may be caused by the structural uncertainties or possible

9. Effect of the modification by titanium dioxide nanotubes with different structures on the fatigue response of Ti grade 2
Nanotechnology is seeing as having potential to raise benefits to several research and application areas. Recently materials with nanostructured surfaces of nanopores, nanotubes and nanowires have become an important investigation field, since their chemical and physical properties may be substantially different from those of the corresponding substrate. In
