Dear colleagues,
The development of society and the improvement of life quality, as well as the overall activities, are unthinkable without development and contribution in the fields of science, scientific research
and educational work. In order to achieve it, personnel and infrastructural potentials are essential, since only they can bring good results, new values and a better future, under condition of having the context of continous and longterm operating, within the ambience of clear and supportive strategies. Therefore, the combination of public governing institutions, academic sector and business entities is
the only proper model, in which all have their essential roles and significance. Institutions can only in mutual connection, and not for the purpose of serving to themselves, offer their true and full contribution to the development of science and research, dissemination of results and their applicability for the benefit of humanity, in general.


In line with the above mentioned, a long-standing mission of MAŠINSTVO is to contribute to the publication of scientific achievements in the field of technical sciences. The direction this Journal wants to follow is to publish quality papers that undergo the mandatory peer-review process, what also aims to achieve another goal: to fulfill the prerequisites for indexation of this Journal.

In this double issue, journal MAŠINSTVO offers four papers from different thematic areas. The first one brings numerical analysis of voltage states of pressure vessels, the second refers on the dynamic analysis of structures, while the third offers an analysis of cutting parameters, and the fourth deals with the analysis of welded joint behavior.


In order to present scientific, research and professional capacities, the Journal follows new trends and practices in multidisciplinary areas. In regard to it, from the previous issue, all papers
are published only in English.


We kindly invite all esteemed colleagues, especially our young colleagues from all universities and other related institutions, to take part and publish their scientific and professional research results in this Journal, which is a significant project of the Faculty of Mechanical Engineering of University in Zenica and provides the opportunity for presentations of scientific research and professional research results from highlighted, and related, thematic areas. The ‘Guidelines for Authors’ section provides basic guidelines for preparing and writing papers. In particular sections, we continue the tradition of presenting scientific, research and economic capacities from the environment.

Sincerely,
Fuad Hadžikadunić, Editor-in-Chief

NUMERICAL ANALYSIS OF STRESS STATE OF PRESSURE VESSEL

Pressure vessels that are exposed to high stresses, due to unfavorable working conditions during exploitation, must be properly designed, taking into account all calculation factors, in order to be safe during their expected lifetime. Checking the condition of the vessel, or analyzing the load of the vessel in working and test conditions, is mandat...

DYNAMIC ANALYSIS OF THE MIXER CONSTRUCTION FOR MIXING LIQUIDS INSIDE THE TANK

The aim of this paper is to perform a dynamic analysis of a large industrial mixer used for mixing liquids inside a vertical tank. The analysis is performed numerically using software tools SolidWorks and Ansys for finite element method analysis. A comparative analysis of results obtained from both software platforms is presented. Although there ar...

INFLUENCE OF CUTTING PARAMETERS ON THE PROCESS OF STYROFOAM CNC CUTTER OPERATION USING EXPERIMENTAL-MATHEMATICAL MODELING

An overview of previous research provides a fundamental understanding of the current state of the process of cutting styrofoam on a CNC cutter, identifying gaps and the need for further research. Identification of important parameters, such as wire cutting speed, density of the styrofoam and current intensity, provide the basis for planning the exp...

WELDED JOINT BEHAVIOR DURING TENSILE TESTING AT DIFFERENT TEMPERATURES

The mechanical properties of steel structures are largely dependent on their operating conditions, with the operating temperature being a crucial factor. Welded constructions require even more attention as the welded joint and its surrounding areas are affected by changes in material during the welding process due to heat input. A study was conduct...
