Technical Glossary Young's modulus(Modulus of elasticity in tension)

[Young's modulus]

Young's modulus is an index to indicate hardness. This value indicates how much force can be exerted per unit area when a certain substance is compressed and its thickness is 0 (this is not actually possible). It is also called the compressive elasticity modulus; if this value is large, the substance can be said to be hard
In general, Young's modulus indicates elasticity in a static state (a state where force that changes with time is not exerted) ; the dynamic value is called the complex compressive elasticity modulus (refer to Complex shear rate).
