Elastic Behavior of Materials – Definition, Example and

Linear elasticity is a mathematical model of how solid objects deform and become internally stressed due to prescribed loading conditions. It is a simplification of the more general nonlinear theory of elasticity and a branch of continuum mechanics. The fundamental "linearizing" assumptions of linear elasticity are: … Se mer Equations governing a linear elastic boundary value problem are based on three tensor partial differential equations for the balance of linear momentum and six infinitesimal strain-displacement relations. The system of … Se mer In isotropic media, the stiffness tensor gives the relationship between the stresses (resulting internal stresses) and the strains (resulting deformations).

NettetLinear elastic solid model. In a linear elastic model, cells are assumed to be in a solid phase with homogeneous and elastic properties. This model is a simplification of the viscoelastic solid model in which the time factor is ignored. The elasticity of the cell can then be represented in terms of its shear modulus .
