Numerical analysis of different weld geometries of lap welded joint in ammonia transport tanks
(Institut za ispitivanje materijala, Beograd, 2017)
Presented is a comparison of stress and strain distribution in lap welded joints of different geometries, which are part of a pressure vessel used as an ammonia transport tank. For this purpose, two numerical models are ...
Numerical analysis of a hypersonic turbulent and laminar flow using a commercial cfd solver
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Computational fluid dynamics computations for two hypersonic flow cases using the commercial ANSYS FLUENT 16.2 CFD software were done. In this paper, an internal and external hypersonic flow cases were considered and ...
Ductile fracture of pipe-ring notched bend specimens - Micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Integrity of pipes is typically assessed by testing fracture mechanics specimens, such as compact tensile (CT) or single-edge notched bending (SENB). However, for some pipe dimensions it is not easy or possible to fabricate ...
