Nonlinear elasticity of silica fibers studied by in-situ Brillouin light scattering in two-point bend test

In-situ Brillouin light-scattering shows that an expression including the fifth-order term is required to capture both minimum in compression and maximum in tension in the elastic modulus of silica glass.

Silica glass exhibits strong nonlinear elastic behavior, meaning that the force–displacement relationship is nonlinear and Hooke’s Law does not apply. In other words, high-order terms are needed to properly describe the elastic behavior of silica glass under high strains:
