Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Integrity assessment of ammonia spherical storage tank
(Elsevier Science Bv, Amsterdam, 2018)
The integrity of the ammonia spherical tank (with a volume of 1800 m3 and the outer diameter of 15120 mm, nominal wall thickness 30 mm) was analyzed due to discovered cracks on the longitudinal and transverse but joints ...
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. ...
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 ...
Numerical analysis of fatigue crack growth in welded joints with multiple defects
(22nd European Conference on Fracture - ECF22 LOADING AND ENVIRONMENT EFFECTS ON STRUCTURAL INTEGRITY Book of Abstracts, 2018)
In the case of welded steel structures (such as pressure equipment), welded joints are often critical location for stress concentrations, due to different mechanical properties and chemical composition compared to the ...
