Finite Element Analysis of Thermal-Mechanical Instabilities in Nonmetallic Friction Composite Material
<p>Thermal-mechanical instability (TMI) has been a research topic of interest as it focuses a lot on transportation systems. Thermal-mechanical instability was first noticed in railway and experimentally studied with a pin-to-pin or pin-to-surface setup of sliding contact. The topic has been …

Thermo-Mechanical Instabilities in Next-Generation Friction Materials in High-Speed Sliding Systems
… enhance thermal properties and minimize thermo-mechanical instabilities (TMI) in high-speed sliding systems. Unfortunately, these metals have adverse environmental effects due to the emission of hazardous particulate matter. As a result, there is a growing movement towards adopting …

Electro-chemo-mechanical instabilities at interfaces in al-solid-state lithium-ion batteries
… pores. Above a critical current density, the mechanical stress at a critically-sized Li-filled flaw tip at the SSE surface can breach the SSE fracture stress to initiate and propagate a crack through which Li penetrates the SSE, until a short circuit occurs. An electrochemo- mechanical model …

Mechanical behavior of elastic rods under constraint
… inside a cylindrical constraint, iii) the mechanical instabilities arising when a rod is progressively injected into a horizontal cylinder, and iv) strategies for mitigation of these instabilities by dynamic excitation of the constraint. First, we consider the role of natural curvature in …

Analysis of Dynamic Surface Instabilities in Soft Hydrogel Cylinders Subject to Laser-Driven Shock-Loading
… loading are known to exhibit a variety of mechanical instabilities which may lead to intricate surface deformation patterns. In particular, creases and wrinkles have been found to play an important role in the morphogenesis of soft tissues and tumor growth. Soft matter instabilities are …

Modeling mechanical dynamics in chain-mediated bacterial sliding
Investigating the mechanical dynamics of bacterial motility has led to a deeper understanding of the behaviors and lifecycle of many bacterial species. We discuss chain driven sliding motility where the bacteria maintain connections between daughter cells following division, resulting in long …

Surface instabilities and interfacial phenomena for nanomanufacturing at the atomically-thin limit
… diverse material properties and superlative mechanical strength. Due to their atomically-thin nature, weak basal plane van der Waals interactions, and vanishing bending stiffness, 2D materials are extremely flexible and thus susceptible to mechanical instabilities that result in deformed …
