visszarugalmasságot

Visszarugalmasság (Ellipticency) refers to a material’s capacity to return to its original shape after being deformed. The term is used primarily in physics, materials science, and mechanical engineering to quantify elastic behavior. It is often measured as the inverse of a material’s bulk modulus or, in the case of solids, as the Young’s modulus for linear elastic deformation.

The concept originates from the Latin “elasticus” and Greek roots meaning “to rebound”. Hungarian scientists in the mid‑twentieth century formalized the notion by deriving the quantitative relations between stress, strain, and the resulting energy stored in a material. Visszarugalmasság is a central parameter in the stiffness equation for springs (k = F/x), where a higher elastic constant indicates a more rigid system.

Applications of visszarugalmasság spread across several fields. In civil engineering, it guides the design of resilient structures that absorb seismic energy. In biomedical engineering, it informs the development of artificial tissues and prostheses that mimic natural elasticity. In industry, the value determines suitable materials for padding, vibration dampers, and high‑precision sensors. Variations in environmental temperature can alter a material’s elastic properties, necessitating the use of temperature‑dependent coefficients in critical calculations.

Measurement typically uses a tensile testing machine or resonant frequency analysis for fine structures. Modern instrumentation measures microelasticity at the nanoscale by means of atomic force microscopy. The derived numbers are often tabulated in engineering handbooks and serve as benchmarks for material selection.

In summary, visszarugalmasság quantifies reversible deformation, playing a pivotal role in design, safety, and innovation across diverse scientific and industrial disciplines.
