Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
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. ...
Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...
Butt welded joints assessment after fire exposure
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. In many cases, after structural safety assessment, fire exposed ...
Effect of laser beam welded reinforcement on integral skin panel fatigue life
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, numerical analyses of fatigue crack growth in integral skin-stringer panel produced by means of laser beam welding (LBW) are presented along with fatigue results verified by previously conducted experiments. ...
Engineering critical assessment of steel shell structure elements welded joints under high cycle fatigue
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Existing flaws in critical parts of structural elements may lead to failures of subassemblies and, in case of lack of redundancy, even to the entire structure collapse. Considering the case of cyclic loading - wind load ...
Numerical simulation of "Hall 1 of the Belgrade Fair"
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper involves the analytical and numerical calculations of the the largest pre-stressed concrete free-standing structure in the world - the Dome of the "Hall 1 of the Belgrade Fair", designed by a well-known Serbian ...
