non-linear mechanics

Non-linear mechanics studies systems where relationships between causes and effects are complex and don't follow straight-line patterns. Unlike simple systems where doubling input doubles output, non-linear systems can produce unpredictable or disproportionate responses. This includes phenomena like chaos, where small changes lead to large effects, or stable patterns that change suddenly. Examples are weather patterns, fluid flow, or material deformation. Understanding non-linear mechanics helps scientists and engineers predict and control these complex behaviors in real-world systems, leading to better designs and innovations across various fields.
