AB  - Most serious weldment failures have catastrophic consequences in terms of damage to other equipment, loss of production, and risks to worker health and safety. For the above reasons, there is a tendency to find the line between safety and disaster, and this requires a guarantee of the integrity of the welded structure even if a crack is present. The structural and mechanical heterogeneity of a welded joint affects its resistance to cracking in both the elastic and plastic regions. Therefore, it is important to define the test method and the position of the fatigue crack. The behavior of an elasto-plastic material, during stable crack growth can be described by the J-Δa diagram. As the crack propagates, a point on the curve is defined, which represents the critical value of the J-integral. The aim of this experiment is to determine JIC value and the procedure is reflected in the determination of the R-curve, i.e., the J‒Δa curve, which consists of the value of the J-integral for uniform crack increments Δa. In this paper, precracked SEN(B) specimens with the fatigue crack positioned in the weld metal (WM) were tested according to standard ASTM E1820 at room temperature (RT), -20 0C and -30 0C.

AB  - Tensile properties of thin plate specimens made from short carbon fiberreinforced PET-G material are experimentally evaluated for various raster angles(printing directions). In additive manufacturing (AM), raster angle is recognized as one of the key printing parameters which strongly influences the strength and stiffness of thefinal part. The relatively high average value of ultimate tensile strength was obtained for specimens printed with the 0° raster angle, compared to the value obtained for specimens printed with the 90° raster angle - 52.2 MPa and 25.4 MPa, respectively. Similarly, noticeably higher average value of modulus of elasticity was obtained for specimens printed with the 0° raster angle, compared to the value obtained for specimens printed with the 90° raster angle - 4752 MPa and 1569 MPa, respectively. Scanning electron microscopy (SEM) was used for analysis of specimens’ fracture surfaces. SEM images revealed considerable volume fraction of voids (porosity). Тhe porosity, together with weak bonding between two adjacent rasters, could be one of key factors for poor tensile properties of samples printed with rasters perpendicular to direction of load application (90° raster angle)

AB  - The main objective of this study is to determine tensile properties of the glass-epoxy polymer composite material. The material is glass fiber 280 g/m², 'twill woven' with 100 cm width, type - Interglas 92125, and epoxy resin type MGS L-135, where samples are molded using hand manual method with 35% fiber weight per volume. Orientations were 0/90° i ±45°. In accordance with appropriate standards, tensile strength and modulus of elasticity were determined. Beside the analysis of the results obtained during the experiment, micro-mechanical analysis of the tensile failure appearance and development was conducted based on the observed cracked surface, which led to a confirmation of all characteristic mechanisms and cracks expected for this type of material and study. Micromechanical analysis performed on the cracked surfaces of the investigated samples, has led to a definition of a structure which is more suitable for exploitation of this material in a presence of this type of external load.

The analysis was done at room temperature, and its results were derived based on the structure of the glass woven 280 g/m², 'twill texture' with the width value of 100 cm, type - Interglass 92125, and epoxy resin type MGS L 135. Samples were shaped by hands with 35% of fabric volume part. The consumed portion of resin was 220 g/m², the thickness of the laminate was 0.308 mm, and the mass of the laminate was 500 g/m2. There were a total of eight layers built in the panel. The micromechanical analysis was derived from the crack surfaces data collected on a scanning electronic microscope, and it showed the mechanisms of damage, and development of cracks until the occurrence of the final break under the tension load.

Ispitivanja su izvedena na sobnoj temperaturi. Analizirani su kompoziti na osnovu epoksidne smole tipa MGS LR 135 i staklenog platna 280 g/m², 'twill' širine 100 cm, tip - Interglas 92125. Uzorci su oblikovani ručnom metodom sa 35% zapreminskog udela vlakana. Utrošak smole je bio 220 g/m², debljina laminata 0,308 mm a masa laminata 500 g/m2. Ukupno je ugrađeno 8 platana u panelu. Analizom prelomnih površina na skening elektronskom mikroskopu izvedena je mikromehanička analiza kojom se došlo do saznanja o mehanizmima oštećenja i razvoju prsline do konačnog loma pri delovanju zateznog opterećenja.

Samples were shaped by hands with 35% of fabric volume part. The consumed portion of resin was 220 g/m², the thickness of the laminate was 0.308 mm, and the mass of the laminate was 500 g/m2. There were a total of eight layers built in the panel. The micromechanical analysis was derived from the crack surfaces data collected on a scanning electronic microscope, and it showed the mechanisms of damage, and development of cracks until the occurrence of the final break under the tension load., Predmet i cilj istraživanja prikazanih u ovom radu su statičko mehanička ispitivanja na zatezanje staklo-epoksi kompozitnog materijala radi dobijanja njegovih relevantnih zateznih svojstava i mikromehaničke analize oštećenja strukture. Ispitivanja su izvedena na sobnoj temperaturi. Analizirani su kompoziti na osnovu epoksidne smole tipa MGS LR 135 i staklenog platna 280 g/m², 'twill' širine 100 cm, tip - Interglas 92125. Uzorci su oblikovani ručnom metodom sa 35% zapreminskog udela vlakana. Utrošak smole je bio 220 g/m², debljina laminata 0,308 mm a masa laminata 500 g/m2. Ukupno je ugrađeno 8 platana u panelu. Analizom prelomnih površina na skening elektronskom mikroskopu izvedena je mikromehanička analiza kojom se došlo do saznanja o mehanizmima oštećenja i razvoju prsline do konačnog loma pri delovanju zateznog opterećenja.",
