Niveljäykkyys
Niveljäykkyys, or stiffness in English, refers to the resistance of a material or structure to deformation under load. It is a fundamental mechanical property that describes how rigid or inflexible a material behaves when subjected to stress. In engineering and material science, stiffness is typically quantified using the modulus of elasticity, often referred to as Young’s modulus, which measures the ratio of stress to strain within the elastic limit of a material.
In the context of mechanical systems, such as springs, beams, or frames, stiffness determines how much a
Niveljäykkyys is also relevant in biomechanics, where it influences the performance of joints, tendons, and other
The concept of stiffness is closely related to other mechanical properties, such as strength and toughness,
