Vetojäykkyyttä
Vetojäykkyyttä refers to the stiffness or resistance to deformation when a material is subjected to tensile stress. It is a fundamental mechanical property that describes how much a material will stretch or elongate under a pulling force before it breaks or permanently deforms. This property is directly related to the material's Young's modulus, which is a measure of its elasticity. A material with high vetojäykkyyttä will experience very little elongation under a given tensile load, while a material with low vetojäykkyyttä will stretch considerably.
The measurement of vetojäykkyyttä is typically performed through tensile testing, where a standardized sample of the
