S355 structural steel is commonly used in fabrication of offshore structures including offshore wind turbine monopiles. Knowledge of mechanical and fracture properties in S355 weldments and the level of scatter in these properties are extremely important for ensuring the integrity of such structures through engineering critical assessment. An interlaboratory test programme was created to
The paper describes tests conducted to identify the mechanisms occurring during the fracture of single-edge notches loaded in three-point bending (SENB) specimens made from an AlTi laminate. The experimental tests were complemented with microstructural analyses of the specimens fracture surfaces and an in-depth analysis of acoustic emission (AE) signals.

Dec 21, 2016 · The stress corrosion of S355 steel in 3.5% NaCl solution under the different strain rates was analyzed with the slow strain rate test (SSRT), the stress corrosion cracking (SCC) behaviors of S355 steel under the different strain rates in the solution were investigated, and the fracture morphologies and compositions of corrosion products under the different strain rates were analyzed Experimental Investigation and Constitutive Description of Mar 10, 2020 · The uniaxial tensile mechanical properties of D1 wheel steel and U71MnG rail steel were investigated experimentally at a wide range of strain rates from 0.0001 to 100 s1. Influence of the strain rate on stressstrain response, ductility, fracture morphology and energy absorption was analyzed and discussed, respectively. Both D1 wheel steel and U71MnG rail steel are demonstrated to be
Jan 01, 2019 · Experimental Programme Base material (BM) of the first experimental plate was a common structural steel S355. Several configurations of layers of a H13 tool steel, in the powder form, were welded on the surface of a plate of the thickness 20 mm. Laser additive welding was performed in all cases under argon protective atmosphere. Friction stir welding of structural steel S235 and S355For the experimental procedure, two of the most used structural steel grades S235 and S355 will be investigated. Present experiments were applied on steel grade S235JR and S355JR, to evaluate the feasibility of FSW application on structural steels. Chemical compositions are presented in Table 1 and Table 2. Table 1. Chemical composition of
This paper presents an experimental investigation into the behaviour of high strength steel structures lighter when compared with using S355, 2.2 million savings in costs and 17% savings in greenhouse gas emissions (Ruukki, 2013). mechanisms such as precipitation hardening on the performance of HSS at elevated temperature is not Microstructures and Mechanical Properties of Friction Jun 21, 2017 · The crack growth exhibited river pattern. It is believed that the fracture mechanism of W2 and W9 in the welding zone was characteristic of a brittle fracture. The impact fracture morphology on the fracture surface of the base material exhibited a fully ductile aspect with fine dimples, as shown in Fig. 16(c). The fracture mechanism of the base

2. Material and experimental procedures . 2.1. Material The carbon steel used in the first part of the experimental work was cut from the platform deck, which had been exposed to a liquid nitrogen spill. The material was a hot-rolled steel of DNV grade NV E36 with plate thickness 12 mm. ResearchGateResearchGate
Sep 01, 2016 · In this paper, the cohesive zone model is used to study the fracture behavior of an S355 electron beam welded (EBW) steel joint. Mechanical properties of different weld regions are derived from tensile tests of flat specimens, which are extracted from the respective weld regions. The cohesive zone model which was applied to predict the damage of the welded joint has two independent parameters, The influence of microstructure on the fatigue crack Jul 28, 2020 · Figure 1A is common Fe-C phase diagram showing important regions in the heat treatment of marine steels. denotes austenite, ferrite and P pearlite. The lines in Figure 1A are straight; in fact, in the case above, they are drawn arbitrarily. In reality, the shape and position of the lines, straight or curved, depend on the steel chemistry, cooling rate and rolling or deformation variables.
