Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma / Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters
(Institut za ispitivanje materijala, Beograd, 2012)
U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel
(Institut za ispitivanje materijala, Beograd, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Final stretch zone width determination for MP35N multiphase alloy
(Institut za ispitivanje materijala, Beograd, 2015)
This paper presents an experimental elastic-plastic fracture behaviour analysis in order to evaluate a resistance of the aged and unaged MP35N alloy to stable and unstable crack growth. MP35N fracture behaviour has been ...
Structural integrity assessment from the aspect of fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2019)
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in ...
