“…Depending on the pattern quality, one has to decide about acceptance of the recorded results. If the quality is satisfactory, the case can be analysed, figures of displacements and strains can be prepared [2]. The method is used as an evaluation for industries, especially the ones dealing with motion and advanced materials.…”

The main goal was to establish results of the individual joint strength characteristics used in composite laminate structure, in order to be used for design computations in airframe structures. A carbon-epoxy composite specimen includes a brass sleeve that is used to connect other metal parts by a bolt, used on light-weight category aircrafts. 11 specimens were tested and pulled by a tensile test machine. The tension mechanisms associated with failure modes of bolted joints in advanced composites is explained. The work is based on experimental test observations, performed by Instron 8516 servo-hydraulic testing machine and analyzed further by Digital Image Correlation (DIC) technique to define failure load of this metal-composite interconnection. Comparison of DIC results is made in parallel with test recorded data as verification. Conclusions include a failure analysis and observations learned during the experiment.READ 2018

“…any kinds of research are devoted at describing the behaviour of crack growth in structural component [1][2][3][4][5][6] and joints [7][8][9][10]. Fatigue crack growth in welded joints is still a very attractive engineering problem, because of the occurrence of various types of crack initiators, such as geometrical and microstructural notches or residual M stresses, as well as the presence of numerous non-metallic inclusions and weld defects.…”

The paper presents the results of experimental fatigue tests performed on welded S355 specimens subjected to combined bending and torsion loading. In order to analyse how the fillet joints' shape and the load ratio affect the crack growth, we selected two kinds of fillet shape: concave and convex, and two load ratios, namely R =-1, 0. Rectangular specimens with stress concentrators in the form of the external two-sided blunt notches and fillet welded joint were tested. The test results were compared to experiments conducted on solid specimens without welds.

The effects of machined circular holes on the mechanical properties and failure characteristics of a unidirectional CFRP were investigated. Our approach was to change the location and the number of holes: (i) a two-set hole was machined with different modes: (A) parallel, (B) 45°and (C) a direction perpendicular to the loading direction; and (ii) multiple holes from n = 0 to 5 were made in the sample parallel to the loading direction. The higher tensile and higher fatigue strengths were obtained for the CFRP sample produced by mode A, compared to modes B and C. This was attributed to the different extend of the maximum stress and stress distribution, caused by the geometrical effects on the sample. The ultimate tensile strength (σUTS) of the sample was well predicted by the geometrical criterion. If the number of holes was increased from n = 0 to n = 2, the tensile strength decreased dramatically. However, the tensile strength did not strongly decrease further for samples with multiple holes from n = 2 to 5. The tensile strength is correlated with the maximum stress adjacent to the hole(s). Those stress values were verified by a 2D digital image correlation and a finite element analysis. Material failure of the CFRP during tensile loading was revealed by nondestructive testing using a piezoelectric ceramic, and debonding of the fibers occurred even at a low applied stress of approximately 35% σUTS.
