Rubber elasticity is the ability of solid rubber to be stretched up to a factor of 10 from its original length, and return to close to its original length upon release. This process can be repeated many times with no apparent degradation to the rubber. [1] Rubber, like all materials, consists of molecules.
Rubber's ability to sustain large deformations with relatively little damage or permanent set makes it ideal for many applications. Pages in category "Rubber properties" The following 31 pages are in this category, out of 31 total.
ISO 3864-4:2011 Part 4: Colorimetric and photometric properties of safety sign materials [4] Part 1 explains how to layout the components of safety signage, dictate the color scheme and sizing information. Part 2 covers the same concepts as part one, but specifically for labels applied on machinery, vehicles and consumer goods.
Biaxial tensile testing is particularly suitable for understanding the mechanical properties of biomaterials, due to their directionally oriented microstructures. [6] If the testing aims at the material characterization of the post elastic behaviour, the uniaxial results become inadequate, and a biaxial test is required in order to examine the ...
In continuum mechanics, an Arruda–Boyce model [1] is a hyperelastic constitutive model used to describe the mechanical behavior of rubber and other polymeric substances. This model is based on the statistical mechanics of a material with a cubic representative volume element containing eight chains along the diagonal directions.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The Yeoh model for incompressible rubber is a function only of . For compressible rubbers, a dependence on I 3 {\displaystyle I_{3}} is added on. Since a polynomial form of the strain energy density function is used but all the three invariants of the left Cauchy-Green deformation tensor are not, the Yeoh model is also called the reduced ...
One type of instrument used to get the abrasion rate and normalized abrasion rate is the abrasion scrub tester, which is made up of a mechanical arm, liquid pump, and programmable electronics. The machine draws the mechanical arm with attached brush (or sandpaper, sponge, etc.) over the surface of the material that is being tested.
