Influence of second-phase particles on fracture behavior of PLA and advanced PLA-X material
(Elsevier Science Bv, Amsterdam, 2021)
Most widespread materials in Additive Manufacturing are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene), which are dissimilar materials in terms of printing abilities and mechanical properties. PLA material ...
Composite material selection for aircraft structures based on experimental and numerical evaluation of mechanical properties
(Elsevier Science Bv, Amsterdam, 2021)
In this paper determination of mechanical properties of composite material using experimental and numerical approach is presented. The mechanical properties of a laminate obtained in the experiment are used for verification ...
Numerical simulation of fatigue crack growth in AA6156 T6 panels
(Elsevier B.V., 2021)
Fatigue crack growth in a panel with 4 stringers and 3-clips, made of AA6156 T6, was modelled numerically using xFEM. The central crack of the length a=17 mm was propagated in the total of 91 steps (in each step crack ...

Analysis of SA 387 Gr. 91 welded joints crack resistance under static and impact load
(Elsevier Science Bv, Amsterdam, 2021)
This paper presents the results of experimental testing of crack resistance of specimens taken from a welded plate made of steel SA-387 Gr. 91, while taking into account different filler materials and welding procedures ...
Numerical analysis of the response of the rc flat slab building under seismic action
(fib. The International Federation for Structural Concrete, 2021)
Investigation of the behaviour of flat slab system has been intensified in the last years. Wide use of flat slab systems due to the fast construction and simplicity of formwork has as the results presence of flat slab ...
Algorithm for defining quality of base material for repair welding
(Institut za ispitivanje materijala, Beograd, 2021)
The paper shows the comparison of different methodologies for defining the quality of base material due for repair welding as one of the basic and initial problems during the repair of damaged parts or machine equipment. ...
Fracture behavior of reactor steel 20MnMoNi 55 in the transition temperature region
(Elsevier B.V., 2021)
The fracture represents the final phase of crack propagation, and the causes of their occurrence or partial crack propagation in the real constructions made of ferritic steels can be different. Along with cracks, influences ...
Numerical simulation of crack growth in a welded joint with defects
(Elsevier B.V., 2021)
Research presented in this paper involves the numerical simulation of crack growth in a welded joint made of common structural steel S235JR2, but with the presence of a number of different welding defects, which represents ...
