Self-loosening behavior of bolt in curvic coupling due to materials ratcheting at thread root
Advances in Mechanical Engineering, 2019 This article presents the bolt self-loosening mechanism in curvic coupling due to the structural ratcheting under cyclic loading. Finite element simulations are carried out under several loading conditions with different preloads and cyclic torque ...

Tribological Study of Chisel Knives in Sandy Soil
Agriculture, 2023 This paper presents the interaction system within the mechanical soil processing process, consisting of two large elements, the metal of the tool and the soil. Due to the two main forces acting on the chisel knives—friction and impact with the sandy soil—

Shakedown analysis of a composite cylinder with a cross-hole [PDF]
, 2011 In this study, both the lower and upper bound shakedown limits of a closed-end composite cylinder with or without a cross-hole subject to constant internal pressure and a cyclic thermal gradient are calculated by the Linear Matching Method (LMM ...

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Myosin's mechanical ratchet [PDF]
Proceedings of the National Academy of Sciences, 2006 Myosin molecular motors bind to and exert force upon actin filaments. Between 24 (1) and 37 (2) myosin subfamilies are currently recognized (3), the myriad members of which are specialized for tasks ranging from muscle contraction through to mechano-sensation and signaling, cell polarization, the sliding and tensioning of cytoskeletal elements ...

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Physical Review E, 2009 Brownian ratchets produce directed motion through rectification of thermal fluctuations and have been used for separation processes and colloidal transport. We propose a flashing ratchet motor that enables the transduction of electrical energy into rotary micromechanical work.

Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).
