Road equipment, such as, e.g., road safety barriers and lighting columns, are subject to certification according to the EN1317 standard to be allowed for use on European roads. In engineering practice, due to the terrain conditions, there are cases where other road equipment is installed within the working width of road safety barriers. Such situations are not considered during the certification process. Hence, the aim of this...

Purpose This study aimed to investigate the geometrical and mechanical properties of human thoracic spine ligaments subjected to uniaxial quasi-static tensile test. Methods Four human thoracic spines, obtained through a body donation program, were utilized for the study. The anterior longitudinal ligament (ALL), posterior longitudinal ligament (PLL), capsular ligament (CL), ligamenta flava (LF), and the interspinous ligament and...

Polymethylmethacrylate (PMMA) is widely used in biomechanics and civil engineering for its properties. While various fillers have been studied to enhance mechanical properties of PMMA, the impact of sand as a filler has been less explored. This study investigates the effects of varying sand content on the mechanical properties and workability of PMMA-based resin composites, assessing their suitability for biomechanical applications....
