Ratchet analysis of structures under a generalised cyclic load history [PDF]
, 2014 This paper introduces a new approach based upon the Linear Matching Method in order to obtain the ratchet limit of structures subjected to an arbitrary thermo-mechanical load history. This method varies from the traditional Linear Matching Method ratchet

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.

On the ratchet analysis of a cracked welded pipe [PDF]
, 2012 This paper presents the ratchet limit analysis of a pipe with a symmetric crack in a mismatched weld by using the extended Linear Matching Method (LMM). Two loading conditions are considered: i) a cyclic temperature load and a constant internal pressure;
