SpletT he deformation behaviour of elastomers is often characterised by specifying the Shore A hardness [1], and less often via the modulus of elasticity.The reason for this is probably because measuring the modulus of elasticity of elastomers by means of the usual methods is not very simple. This fact must be viewed in light of the practical interest to know the … SpletDescription. The Young modulus of a material is an intrinsic, bulk property that describes how the material deforms when subjected to stress. It relates the size of the applied compressive or tensile stress to the corresponding strain. The larger the Young modulus, the less a material deforms to a given stress, i.e. the stiffer the material.

Splet26. nov. 2024 · The latter relates to rigid materials whereas the A scale relates to bendable rubbers. Shore hardness is measured with a device known as a Durometer, hence the term ‘Durometer hardness’. Hardness value is determined by the penetration of the Durometer indenter foot into the sample being tested. The resilience of rubbers and plastics means ...

Splet12. nov. 2024 · The equation for Young's modulus is: E = σ / ε = (F/A) / (ΔL/L 0) = FL 0 / AΔL. Where: E is Young's modulus, usually expressed in Pascal (Pa) σ is the uniaxial stress. ε is the strain. F is the force of compression or extension.
