... it, and are welded to reinforce the damaged pipe underneath. Type B sleeves have fillet welds which attach the sleeves to the carrier pipe and allow them to contain pressure if a leak occurs under the sleeve. Type A sleeves only reinforce the circumferential integrity of the pipe, restoring the ability to sustain...

.... The algorithms of mismatched thermal strain (MTS) and thermal contraction strain (TCS) are adopted to estimate longitudinal and transverse thermal strains. A thin plate with fillet-welded stiffeners (2006) were modeled to investigate strategies for computationally efficient welding simulation in the context...

... propagation at fillet welds, based on finite element (FE) analysis. A series of transversely loaded butt welds are selected as FE models, because stress increase at the toe of butt welds is just equal to the NDS. For simulating the crack growth at the fillet welds, geometric parameters of the butt welds...

... strength on fatigue strength for the weld joints, series of fatigue test were conducted on the specimens of butt weld joint and longitudinal fillet weld joint with the different plate thickness and tensile strength steel. From the test results of each series of specimens which were taking into account...

...ABSTRACT Fillet welds with longitudinal stiffeners are a type of weld detail which is of great importance in practice. The fatigue performance of welded constructions is usually depending strongly on the properties of the worst weld details whereas fillet welds and especially longitudinal...

The SIF of a crack in a fillet weld derived from the IF database constructed by the developed system agrees well with the direct FE analysis result. These show...

... was developed to assess fatigue strength of fillet welded joint to reduce cyclic time and costs. Stress corrosion cracking susceptibility was also evaluated in a sour environment using C-rings and Slow Strain Rate Testing (SSRT). Based on the test results, an age hardened Ni-base alloy was selected for sour...

... sufficient cross-sectional area due to larger fillet welds. Tests on BH-1 and BH-2 concern the applicability of PJP groove welds for beam-to-column connections. The third specimen had a wide flange beam field-welded to a cold-formed square hollow section column (SHS) (BS-3). BS-3 had an internal diaphragm...

.... The stress intensity factor was calculated by just two elements through the plate width, and compared with the conventional reference. The second example is a T-joint with fillet welding under uniaxial uniform tension at far two ends of the flat plate. Hot spot stress at the welded zone was calculated...
