Mechanisms and Materials for NTE [PDF]
Frontiers in Chemistry, 2018 Negative thermal expansion (NTE) upon heating is an unusual property but is observed in many materials over varying ranges of temperature. A brief review of mechanisms for NTE and prominent materials will be presented here. Broadly there are two basic mechanisms for intrinsic NTE within a homogenous solid; structural and electronic.

A New Resultant Vibration Acceleration Model of a Planetary Gear Train and Fault Response Analysis
Shock and Vibration, 2022 A new resultant vibration acceleration model is proposed to reveal its signal characteristics more accurately in the healthy and faulty state. First, an analytical lateral-torsional coupled dynamic model is developed with consideration of time-varying ...

Exploiting elastic buckling of high-strength gold nanowire toward stable electrical probing
iScience, 2022 Summary: Buckling is a loss of structural stability. It occurs in long slender structures or thin plate structures which is subjected to compressive forces. For the structural materials, such a sudden change in shape has been considered to be avoided. In

Mechanics and materials in fretting
Wear, 1992 Materials fail through overstressing and overstraining. Overstressing leads to crack initiation and later propagation which can cause failure. Overstraining leads to material transformation, for instance strain hardening, followed by changes in material properties such as toughness loss.

Mechanics of Interfacial Composite Materials [PDF]
Langmuir, 2006 Recent experiments and simulations have demonstrated that particle-covered interfaces can exist in stable non-spherical shapes as a result of the steric jamming of the interfacially trapped particles, which confers the interface with solid-like properties. We provide an experimental and theoretical characterization of the mechanical properties of these
