Continuum mechanics stress
Web3. Kinematics – mathematical description of motion and deformation. The continuum; Inertial reference frames; the reference configuration and current configuration of a deformed solid. The displacement and velocity field, examples of deformations and motions, Eulerian and Lagrangian descriptions of motion. WebContinuum mechanics studies the foundations of deformable body mechanics from a mathematical perspective. It also acts as a base upon which other applied areas such as solid mechanics and fluid mechanics are developed.

Webidentify additional pairs of energetically conjugate stresses, strains, and strain-rates. We already have the Cauchy stress and the rate of deformation tensor as our first energetically conjugate pair. This is logical because both are related to the deformed and rotated configuration of an object. 1st Piola Kirchhoff Stress WebNov 26, 2024 · 2 Answers Sorted by: 3 Thermal expansion of a constrained object can produce nonzero stress with zero strain, for example. This occurs because generalized …
WebApr 21, 2016 · Therefore the stress rate is not objective unless the rate of rotation is zero, i.e. is constant. There are numerous objective stress rates in the literature on continuum mechanics - all of which can be shown to be special forms of Lie derivatives. However, we will focus on three which are widely used.
