Cyclic Loading of Jammed Granular Systems
Materials, 2022 This article describes the cyclic loading of jammed granular systems represented by vacuum-packed particles in compression and tension, focusing on the influence of the properties of the granular material on the mechanical response. A jammed granular system is represented by a cylindrical sample filled with polymer granules (vacuum-packed particles ...

Experimental investigation of preload losses in high strength bolts under cyclic loading
Građevinar, 2021 Slip-resistant shear connections with preloaded bolts have traditionally been used in steel structures exposed to cyclic. Hence, shear load is transferred through friction surfaces rather than through contact between the bolt surface and the hole.
