NettetAn elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved … 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). For an isotropic medium, the stiffness … Se mer For anisotropic media, the stiffness tensor $${\displaystyle C_{ijkl}}$$ is more complicated. The symmetry of the stress tensor $${\displaystyle \sigma _{ij}}$$ means that there are at most 6 different elements of stress. Similarly, there are at most 6 different … Se mer trouwnummersNettetWhat does non linear elastic mean? The first question was answered above: non-linear elastic means non-linear relation between stress and strain, which is followed upon … trouwriem

"Nettetpurely elastic in the conditions tested, so that the current strain depended only on the current stress (or vice -versa), and not on past conditions. This allows us to use algebraic equations to relate stress to strain. However, many materials are actually . viscoelastic, meaning that they have both elastic and viscous properties.
