= Infinitesimal strain theory
{wiki=Infinitesimal_strain_theory}
Infinitesimal strain theory, also known as small strain theory, is a fundamental concept in solid mechanics that deals with the deformation of materials under small loads or displacements. It assumes that the deformations are small enough that the linearization of the strain and displacement fields is valid. This theory is widely used in engineering applications, particularly in structural analysis, geotechnics, and materials science.
