“…Furthermore, the blunting occurs in the elastoplastic region (Figure 4b-i). As a result of blunting in the second stage, shear deformation of the root-stretch zone is observed [35] (Figure 4j). In the third stage, crack initiation occurs (Figure 4k), which in the fourth stage increases its length through stable growth.…”

The work is focused on experimental research of deformation characteristics on three grades of hot-dip galvanized steels for the automotive industry. Deformation maps were obtained using the DIC (Digital Image Correlation) method. The map documents the development of longitudinal and transverse deformations under tensile stress. In addition to uniaxial tension, the investigated specimens were subjected to eccentric tension. The stable crack growth (SCG) was evaluated using a non-contact measurement technique on CT (compact tension) specimens. The deformation of steels, which affects the resistance to stable crack growth (confirmed by the Design of Experiments—DOE method), was manifested in the first stages of eccentric loading of specimens. The notch root radius varies considerably due to the blunting of the starting fatigue crack. The resistance to stable crack growth, which represents a safety reserve during a vehicle crash, was obtained.

“…During the test, the test specimens were exposed to the tensile load at the speed of 100 mm/min until the rupture occurred, at the ambient temperature. During the test, a video extensometer (vidoeXtens) was used to measure the elongation [24] of the predefined length of the working section of the test specimen which was marked with white reference lines drawn using a template. Three test specimens were prepared for the test; they were cut out of the conveyor belt in the transversal direction and the basic mechanical properties of these test specimens were determined.…”

The effect of the impact load exerted by the baggage impacting light baggage carousels may be manifested as mechanical damage to the carousel as a result of the stress-strain processes. In order to describe the phenomena related to the baggage impact, it is important to monitor the tensile strength of rubber carousels of light conveyor belts intended for the conveyance of baggage at airports. The output of the article is monitoring the mechanical load of the carousel, the comparison of the results thereof with the outputs of the CAE analysis, as well as the determination of the optimal material model and the approximation thereof to the experimental model.

“…The grooves are free to broaden due to radial pressure when the muscle is being filled. Tensile forces are transmitted through extremely strong polymer fibres located in every groove of the membrane [15][16][17]. Such pneumatic artificial muscle was named the Pleated Pneumatic Artificial Muscles-PPAM.…”

Current efforts are focused on assembling new constructions while applying non-conventional actuators, for example, artificial pneumatic muscles, in engineering manufacturing processes. The reason is to eliminate stiffness and inflexibility of equipment structures that make sharing the working space of the technological equipment complicated. This article presents the results of experimental measurements of pressures in artificial muscles and rotations of the actuator with artificial muscles at various loads, using a testing device of an antagonistic actuator. The measurement results were used to create the function of the course of the static property of the antagonistic actuator with artificial muscles of the Festo type and to determine a mathematical model of the actuator dynamics, while applying the method of least squares.
