Elastic modulus of halloysite nanotubes [PDF]

Nanotechnology, 2013
This work reports measurements of the elastic modulus of halloysite nanotubes. Nanoscale three-point bending tests were performed on individual nanotubes using an atomic force microscope. Nanotubes exhibit elastic behaviour at small deformations. The stiffness of the tubes, and hence their elastic modulus, was deduced from force curve measurements ...

Elastic Modulus of Polypyrrole Nanotubes

Physical Review Letters, 2000
The first measurements of the tensile elastic modulus of polypyrrole nanotubes are presented. The nanotubes were mechanically tested in three points bending using atomic force microscopy. The elastic tensile modulus was deduced from force-curve measurements on different nanotubes with outer diameter ranging between 35 and 160 nm.

Temperature-porosity-dependent elastic modulus model for metallic materials

Reviews on Advanced Materials Science, 2022
Elastic modulus plays a key role in the application of porous metallic materials. However, to the best of our knowledge, few attempts have been made to model the simultaneous dependence of elastic modulus on temperature and porosity for metallic ...

STUDY ON THE QUANTITATIVE MODEL OF THE ELASTIC MODULUS OF OIL SHALE DURING PYROLYSIS – A CASE STUDY OF FUSHUN OIL SHALE; pp. 327–338 [PDF]

Oil Shale, 2018
The decrease of the elastic modulus of oil shale during pyrolysis was mainly caused by pyrolysis of kerogen and the deterioration of the oil shale skeleton at high temperature.

Elastic Modulus Prediction Model of Foamed Concrete Based on the Walsh Formula

Applied Sciences, 2022
Foamed concrete consists of cement matrix and air-foam and has more complicated structure characteristics than normal concrete. However, current research on the elastic modulus of foamed concrete is still limited to empirical equations.

An analysis of the elastic properties of a porous aluminium oxide film by means of indentation techniques [PDF]

, 2013
The elastic modulus of thin films can be directly determined by instrumented indentation when the indenter penetration does not exceed a fraction of the film thickness, depending on the mechanical properties of both film and substrate.

Permeability and dynamic elastic moduli of controlled porosity ultra-precision aerostatic structures [PDF]

, 2014
Porous ceramic aerostatic bearings enable precise and smooth motion and improved stiffness compared with widely used orifice restrictor bearings. However, the processing techniques so far used are too complex or rely in lowering the sintering temperature

Calculation method of elastic modulus for carbon fiber-reinforced plastics considering inhomogeneous interphase

Science and Engineering of Composite Materials, 2022
The characteristic of interphase has a significant influence on the macroscopic performance of carbon fiber-reinforced plastics (CFRP). To investigate the effect of interphase on composite elastic modulus, a representative volume element (RVE) of ...
