Kelvin-Voigt model

The Kelvin-Voigt model describes how certain materials deform and recover when a force is applied. It combines two elements: a spring (which resists deformation elastically) and a damper (which resists flow or movement viscously). When stress is applied, the material stretches like a spring, but also experiences a delay or resistance like a damper. This model helps predict how materials like polymers or biological tissues respond over time, capturing their ability to both stretch and gradually return to shape after the force is removed, illustrating a combination of elastic and viscous behavior.
