Repairing of cracks on tooth gear ring of a bucket-wheel excavator
(Elsevier B.V., 2023)
Bucket-wheel excavators are continuously working machines for removal of waste and useful materials in open-pit mines, mainly used for mining of lignite. The purpose of a tooth gear ring is to rotate the excavator using ...
Finite element and fracture mechanics analysis of a cracked oil-storage tank
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, 2023)
Stress distribution, as obtained by the finite element method (FEM), and corresponding fracture mechanics parameters, have been used to assess integrity of a pressure vessel. Once the stress distribution is known, the most ...
Predicting fatigue crack growth in complex geometries using numerical methods
(Procedia Structural Integrity, 2023)
Fatigue cracks growth in three different wing spar geometries is simulated using xFEM, as the most suitable numerical method for this purpose. The goal of this analysis was to find out how crack paths affect number of ...
