That depends on the hardness (durometer) of the rubber. It can be quite low and range from 100 psi to over 1000 psi. If it is very thin, then since it is nearly incompressible (poisson ratio approaches 0.5) then the modulus increases to a much higher value, depending on thickness , and can vary from 1000 psi to 10000 psi in general, and approach over 300,000 psi in the limit.
You need to know the dimensions and durometer.
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
Young's modulus
1. Young's modulus of elasticity, E, also called elastic modulus in tension 2. Flexural modulus, usually the same as the elastic modulus for uniform isotropic materials 3. Shear modulus, also known as modulus of rigidity, G ; G = E/2/(1 + u) for isotropic materials, where u = poisson ratio 4. Dynamic modulus 5. Storage modulus 6. Bulk modulus The first three are most commonly used; the last three are for more specialized use
Yes, if the material is very thin in ther axis of compression. If it is not thin, as in compressing a long cyclinder, you do not need to know bulk modulus. If very thin it won't make a lot of difference if it a metal with usual poisson ratio of about 0.25, but will make difference for possion ratio higher, especially approaching 0.5, as in rubber. In the case of the long cyclinder stress = modulus xstrain In the case of the thin material stress = modulus x strain times the quantity (1-u)/ ((1+u)(1-2u)) where u = poisson ratio; the relation to bulk modulus for u is u =1/2 - E/6B where B = bulk modulus and E = elastic modulus

Kevlar has improved the abrasion resistance, tear strength, modulus, chip resistance and rubber strength.
By rubber, low-density, diatom polyethylene, diatom frustules (largely silicic acid), and PFTE (Teflon).
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
Rubber is used as vibration absorbers, because rubber has a relatively high shear modulus compared to other materials. That means when a rubber material is shear stressed, i.e. stressed parallel to its cross-section, rubber can be stressed more before it becomes permanently deformed.
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
The Young modulus and storage modulus measure two different things and use different formulas. A storage modulus measures the stored energy in a vibrating elastic material. The Young modulus measures the stress to in still elastic, and it is an elastic modulus.
N0. The common belief is that if an object elongates easily the object is more elastic . But in Physics the object which gives more resistance to elongate is said to be more elastic . Such objects will have high Young's modulus . Steel is more elastic than copper . The Young's modulus for steel is 210 G Pa For copper it is 117 G Pa Elongation for steel is 35% and for copper it is 45% For rubber Young's modulus is 0.02 G Pa and elongation is 500 % During collision two clay balls will stick together. We call it inelastic collision . Two steel balls will rebound easily and the collision is elastic collision.
Young's modulus
Contrary to popular expectation, rubber is not really elastic, atleast not the way scientists define elasticity. Rubber is actually much less elastic than steel. Thus for best results we use steel or similar materials, say brass, in this experiment.
