Layered elastic theory

Layered elastic theory describes how materials made of multiple elastic layers respond to forces. Imagine stacking flexible sheets; each layer deforms differently based on its properties, but the overall structure behaves predictably. The theory helps analyze how stress and strain distribute through these layers when subjected to forces, considering each layer’s elasticity (its ability to return to shape). This approach is useful in engineering and geophysics to model complex layered systems like soil, rocks, or composite materials, ensuring structures can withstand loads safely by understanding how forces move through each layer.
