The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

This file type includes high resolution graphics and schematics when applicable. However, this relationship between stress and strain in a material is linear only when the force applied is within ...

Researchers have developed a hydrogel composed of poly(N-acryloylglycinamide) (PNAGAm) grafted with arginine (R)–glycine (G)–aspartic acid (D)–serine (S) peptide whose elastic modulus can be changed ...

Instrumented indentation, or nanoindentation, is an important technique used for measuring the mechanical properties of materials, and can be conducted in situ even on the circuit board itself. This ...

Microspheres have a wide range of uses in modern life. For example, the density of manufactured materials is lowered using hollow microspheres. In present-day liquid chromatography, the analyte is ...

City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar ...

When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...
