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...

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...

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...

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...

There are many ways to accomplish optimization of machining process. In the experimental part of this paper, the optimization of machining process is accomplished from the aspect of cutting conditions, which are independent variables (speed, feed, and cutting depth), whereas the dependent variables refer to the surface roughness, more precisely, ar...

This paper shows optimization by using the Monte Carlo method, the mathematical model of roughness, or the mean arithmetic deviation of the profile. Optimization means finding the best of all possible solutions. According to the experiment plan, an experimentwas previously performed. Based on the results of the experiment and the plan matrix, the c...

In this paper, a differential equation is derived that gives the relationship among the Loschmidt constant, the Avogadro constant, and the speed of sound in real gases as a function of the thermodynamic properties of the gas (pressure, temperature, and volume). The constant ratios NL/NA and the relative deviation of the NL/NA ratio from the mean va...

In the time of the world’s growing need for multilingualism it is necessary to examine all possibilities for teaching foreign languages in a faster and more efficient manner. Instead of passive users, we need engineers who actively use foreign languages. CLIL is an approach that insists on economization of time needed for foreign language acq...

Fracture mechanics is a field that is increasingly studied and applied in modern industry. One of the most widely accepted methods for assessing structural integrity in this field is the SINTAP method. Although there are many literary sources available that discuss thismethod, very few of them present its concrete application. This paper presents t...

The paper aims to explain the concepts related to proving and to permanent court expert witnesses, as a means of proving in the legal system of Bosnia and Herzegovina, on the basis of the legal and legislative framework that is a prerequisite for the performance of expert witnesses work in Bosnia and Herzegovina. The paper starts with: the conditio...
