TESTING THE ATTITUDE TOWARD THE USE OF E-COMMERCE BASED ON THE CUSTOMER’S EDUCATIONAL LEVEL: THE CASE OF THE REPUBLIC OF SERBIA

The subject of this paper is to examine to what extent and in which way educational level influences the use of e-commerce in the Republic of Serbia, as well as, in part, to examine customer satisfaction with e-commerce. The main objective of this paper is to determine the level of customer use of e-commerce depending on their educational level, as well as to spot the areas which need to be improved in order to increase the degree of use of e-commerce in the Republic of Serbia. For the purposes of sorting and grouping the data in this study the statistical method has been used. All collected data were processed in the statistical software SPSS (descriptive and parametric analyses were used, as well as comparison of mean values, correlation and regression). Based on the results of the tests conducted it is to conclude that the respondents generally use e-commerce in Serbia on a small scale and that other technological advances are accepted to a greater extent than e-commerce. The respondents have very low confidence while using e-commerce. One of the reasons for such a situation is the fear of possible abuses or the fear that e-commerce is insecure. Therefore, in order to increase e-commerce in Serbia, one of the priorities should be work on increasing the security of participants in e-commerce to reduce the possible abuses. From the research a conclusion can be drawn that the level of education significantly affects the use of e-commerce in Serbia and that it should be constantly worked on raising the educational level of the citizens in order for them to be able to properly use the advantages that e-commerce offers

Experimental Determination of the Critical Value of the J-Integral that Refers to the HSLA Steel Welded Joint

Fracture mechanics, as a scientific discipline dealing with the study of cracks in welded structures, has defined parameters and introduced new test methods in order to better determine the tendency to crack growth, critical conditions for rapid fracture development, material resistance to rapid crack propagation and better definition of other parameters for assessing the behaviour of the material and the safety of the structure in the presence of cracks. In this paper, the focus is on determination of the parameter of elastic-plastic mechanics of J-integral, more precisely, on examination of the critical value of J-integral (JIc) of the welded joint of HSLA steel. The position of the tip of the fatigue crack and the properties of the region where fracture propagation occurs are main indicators of influence of the heterogeneity of the NN-70 welded structure and mechanical properties. Resistance to cracking in the welded joint shows that the heterogeneity has a major impact on the resistance to crack initiation and propagation, in elastic as well as in the plastic region

Determination of the Coffin-Manson equation under low-cycle fatigue conditions

The cycle loading of a material results in the modification of its properties and so in this paper is presented the behaviour of the fatigue life using low-cycle fatigue parameters. By applying the Coffin-Manson equation in fatigue loading of the tested specimens, the crack initiation has been computed. The stabilized hysteresis loop is a characteristic of all hystereses and it is used to determine all of the parameters for the low cycle fatigue (LCF) assessment. The experimental results have given us important information on the understanding of fatigue behaviour of high strength low-alloyed steel (HSLA) and its welded joints

Processing of Data Obtained by the Testing of Steel under Low Cyclic Fatigue (Part I)

The design of mechanical components exposed to fatigue load, at a low number of cycles, requires knowledge of the behaviour of the material under the impact of variable load in conditions of controlled strain when cyclic plasticity is present. The aim of testing the quality of the material of the components exposed to low cycle fatigue (LCF) in many industries: nuclear, aerospace, mechanical, civil engineering and shipbuilding. In order to ensure the reliability and consistency of the results from different laboratories, it is necessary to collect all test data using test and data processing methodologies that are in accordance with a number of key points of ISO 12106:2017 and/or ASTM E 606-04 standards. This paper defines a new data processing methodology after the LCF testing of steel
