Characterization of heat affected zones produced by thermal cutting processes by means of Small Punch tests
Thermal cutting processes introduce changes in the heat affected zone (HAZ), which can lead to a significant reduction of the service life of components. In... Read More
Failure Analysis of High Strength Galvanized Bolts Used in Steel Towers
This paper analyses the failure of three bolts used in the structural connections of a number of steel towers located in northern Europe. The analysis... Read More
Fatigue behaviour and BS7608 fatigue classes of steels with thermally cut holes
Thermal cutting includes oxy-fuel, plasma and laser cut technologies. These cutting methods generate cut surfaces and material transformations that determine the final fatigue behaviour of... Read More
Fracture assessment of notched short glass fibre reinforced polyamide 6: An approach from failure assessment diagrams and the theory of critical distances
This paper provides a structural integrity assessment methodology for the analysis of notched short glass fibre reinforced polyamide 6 (SGFR-PA6). The proposal combines the use... Read More
SED criterion estimations of fracture loads in structural steels operating at lower shelf temperatures and containing u-notches
This paper presents the application of the Strain Energy Density (SED) criterion for the estimation of fracture loads on structural steels S275JR and S355J2 operating... Read More
Notch effect on the fracture of several rocks: Application of the Theory of Critical Distances
The paper analyses the fracture behaviour of several rocks, namely a sandstone, a limestone and two marbles, one of them being a Carrara marble. The... Read More
Some default values to estimate the critical distance and their effect on structural integrity assessments
When the structural integrity of notched components is analysed, it is generally assumed that notches behave as cracks, something which generally provides overconservative results. Thus,... Read More
Experimental investigations of the influence of laser beam and plasma arc cutting parameters on edge quality of high-strength low-alloy (HSLA) strips and plates
The paper deals with experimental investigations of the influence of laser beam and plasma arc cutting parameters on edge quality of a range of steel... Read More
Unified two-stage fatigue methodology based on a probabilistic damage model applied to structural details
Fatigue cracks are often a result of incremental stable crack growths that can be described by fracture mechanics. Fatigue crack initiation, however, has been most... Read More
