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.

Mechanical couplings of 3D lattice materials discovered by micropolar elasticity and geometric symmetry [PDF]
, 2022 Similar to Poisson's effect, mechanical coupling is a directional indirect response by a directional input loading. With the advance in manufacturing techniques of 3D complex geometry, architected materials with unit cells of finite volume rather than a point yield more degrees of freedom and foster exotic mechanical couplings such as axial-shear ...

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.

Mechanical Alloying: Processing and Materials [PDF]
Metals, 2021 Mechanical alloying is a technique involving the production of alloys and compounds, which permits the development of metastable materials (with amorphous or nanocrystalline microstructure) or the obtention of solid solutions with extended solubility [...]

The contribution and FIP bias of three types of materials inside ICMEs associated with different flare intensities [PDF]
arXiv, 2023 The studies on the origination and generation mechanisms of ICME materials are crucial for understanding the connection between CMEs and flares. The materials inside ICMEs can be classified into three types, coming from corona directly (corona-materials), heated by magnetic reconnection in corona (heated-corona-materials), and generated by ...

Mechanics of filled cellular materials [PDF]
Mechanics of Materials, 2016 Abstract Many natural systems display a peculiar honeycomb structure at the microscale and numerous existing studies assume empty cells. In reality, and certainly for biological tissues, the internal volumes are instead filled with fluids, fibers or other bulk materials.
