Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
Experimental stress-strain analysis of composite beams
(Croatian Society of Mechanics, 2013)
Numerical modelling of crack propagation in friction stir welded joint made of aluminium alloy
(Elsevier Science Bv, Amsterdam, 2014)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded (FSW) joints has been numerically modelled. Crack propagation in unstiffened part of the structure between two ...
Measurement Uncertainty of Fast Pulse Voltages Measurements with Capacitive Divider
(Institute of Electrical and Electronics Engineers Inc., 2017)
Causes of measurement uncertainties might be numerous and as the rule, not all of them can be considered. Two basic types of measurement uncertainty are the type A and the type B. Measurement uncertainty of type A is ...
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 ...
Effect of Exploitation Conditions and Flaw Geometry on the Load Carrying Capacity of Casing Pipes for Oil Drilling Rigs
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The subject of this work is examination of API J55 steel casing pipes manufactured by high frequency (HF) contact welding. Since the pipes were withdrawn after about 70 000 hours of service in an oil drilling rig, the ...
Characteristics' optimization of gas-filled surg arresiers by using gas mixtures
(Institute of Electrical and Electronics Engineers Inc., 2015)
The increasing trend of electronic components' miniaturization makes them unresisting to overvoltage occurrences. Therefore, it is necessary to pay special attention to overvoltage protection at the low-voltage level. ...
Calculation of maximum tensile and shear forces in restorative materials using finite element method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The purpose of this paper was to determine tensile loading that leads to dental restoration failure, i.e. the critical values of stress. In order to analyze stress distribution within the restoration and tooth, mechanical ...
Numerical Analysis of Thermal Conditions for Planning and Further Improvements of Hard Surfacing Experiment
(Amer Inst Physics, Melville, 2013)
An initial goal of this study was to use the results from an existing experiment and to set up as complete as possible the numerical model for the thermal analysis of a hard surfacing process. It was clear from the start ...
