Fatigue Life Estimation of Damaged Integral Wing Spar Using XFEM
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
This paper presents the application of the extended finite element method (XFEM) in crack propagation simulation on the integral wing spar that should replace existing differential spar of the light aircraft UTVA 75. ...
Application of Fracture Mechanics Parameters to Spherical Storage Tank Integrity Assessment
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Fracture mechanics parameters have been applied to assess pressure vessel integrity. The pressure vessel analysed here was the ammonia spherical tank (volume of 1800 m(3), outer diameter 15.12 m, thickness 30 mm) where ...
Stress Intensity Factors Evaluation at Tips of Multi-Site Cracks in Unstiffened 2024-T3 Aluminium Panel Using XFEM
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
The aim of this paper was to establish and demonstrate significant capacity and performances of extended finite element method (XFEM) to calculate stress intensity factors (SIFs) histories versus crack length for problems ...
Crack Growth Rate Analysis of Stress Corrosion Cracking
(Univ Osijek, Tech Fac, Slavonski Brod, 2021)
A theoretical film rupture model was used for computational procedure to predict the crack growth rate within the Stress Corrosion Cracking (SCC) conditions. Chemical, electrochemical and mechanical aspects of the SCC were ...
