Failure analysis of the combat jet aircraft rudder shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper analyzes failure causes of the combat jet aircraft rudder shaft (RS) which occurred during the flight mission. A finite element method (FEM), utilized to determine the stress state of the RS subjected to hinge ...
Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
Failure analysis of an aircraft engine cylinder head
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The piston engine of the training aircraft malfunctioned during the flight due to the cracking of its cylinder head (CH), which is manufactured from an aluminum casting alloy. Based on the fractographic examination of the ...
An investigation of the repetitive failure in an aircraft engine cylinder head
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Cylinder head (CH) failures in aircraft piston engine may have serious or fatal consequences to the safety of the crew and the aircraft. Moreover, when failure becomes undoubtedly repetitive and critical resulting in loss ...
The synergistic effects of hydrogen embrittlement and transient gas flow conditions on integrity assessment of a precracked steel pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
We are reporting in this study the hydrogen permeation in the lattice structure of a steel pipeline designed for natural gas transportation by investigating the influence of blending gaseous hydrogen into natural gas flow ...
Fatigue fracture analysis of helicopter landing gear cross tube
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper presents the failure analysis results of the helicopter skid landing gear. The helicopter skid landing gear fractured while the helicopter was on the ground at the airport. The aft cross tube of the landing gear ...
Probabilistic analysis of corroded pipeline under localized corrosion defects based on the intelligent inspection tool
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
A methodology is developed in this paper to estimate the time-dependent reliability of a pipeline in Algeria, which is in exploitation from 1981 and with internal and external localized corrosion defects detected in 2009. ...
Failure analysis and reconstruction design of the slewing platform mantle of the bucket wheel excavator O&K SchRs 630
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The slewing platform is the fundamental part of the bucket wheel excavator (BWE) structure. The occurrence and propagation of cracks in the zones of the slewing platform mantle holes, may probably lead to BWE collapse. The ...
