A structural integrity model for hydrogen embrittlement of low carbon steel and the combined effect of help and hede mechanisms on macromechanical properties
(International Conference on Fracture, 2017)
A large number of contemporary studies about hydrogen embrittlement confirmed the multiple effects of hydrogen and activity of the different hydrogen embrittlement mechanisms in low carbon steels. However, critical evaluation ...
Fracture behaviour of S316L stainless steel thin plates
(International Conference on Fracture, 2017)
Experimental investigation was conducted on thin CT specimens made of S316L stainless steel, well known for good corrosion and reasonable fracture properties. Standard fracture mechanics testing is performed, and compared ...
Material characterization of the main steam pipeline made of 12%Cr tempered martensite ferritic steel after prolonged service
(International Conference on Fracture, 2017)
In the past decades, tempered martensitic ferritic steels with 9-12% chromium and containing carbide stabilizing elements have been widely used for components which operate within the creep range in power and industrial ...
Creep crack growth - Comparison of two steel P91 and P22
(International Conference on Fracture, 2017)
The deformation and crack growth behaviour of P22 and P91 steel weldments tested at 550 °C and 600 °C, respectively,compact C(T) type specimens with sharp EDM starter notches in the base metal (BM) and heat affected zone ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(International Conference on Fracture, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
The new experimental testing methodology for conveyor idler's fits control
(International Conference on Fracture, 2017)
The most common way to transfer tangential and axial loads in different types of assemblies is by interference fits. It is essential to determine interference fit parameters of pressed joints, which provides a proper ...
Temperature and time effects on fatigue strength of weldments
(International Conference on Fracture, 2017)
Temperature and service time effects on A-387 Gr. B Cr-Mo steel weldment fatigue strength have been evaluated. To assess service time effect on fatigue strength, samples are take from 40 years “old” material, whereas ...
Temperature and time effects on fracture toughness values in welded joint
(International Conference on Fracture, 2017)
Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic ...
Influence of the 3D interface crack front shape on the fracture parameters
(International Conference on Fracture, 2017)
Mechanical properties of multi-layer materials are often restrained by the strength of the interface between the constituting materials. Interface is frequently a spot of the crack initiation and delamination usually starts ...
Fatigue crack growth in aluminum alloyt welded joint
(International Conference on Fracture, 2017)
The aim of the present investigation is to study the fatigue crack growth of welded T joints made of AA2024-T351 aluminum alloy. Three dimensional finite element models, with cracks as initial defects, will be constructed ...
