Once the strain tensor is defined, one needs to use the constitutive relation which at linear level relates the strain tensor to the stress tensor \sigma_{ij}: \begin{equation}\sigma_{ij}\,=\,C_{ijkl}\,\varepsilon^{kl}\,+\,\dots, \tag{13}\end{equation} with C_{ijkl} being ...

(Navier–Stokes) equations for incompressible flow, respectively given in vector form by(10)divu=0,(11)ρDuDt=divT+ρgB−gradP,where ρ is the liquid density, uis the velocity, T is the shear-stress tensor, gB is the buoyant acceleration created by the bubbles, and P is the pressure...
This article further discus-Ses reliability calculation of the Simple Rigid Frame in the stress redistribution case. We obtain reliability calculation formulas of the Simple Rigid Frame structural system, and give numerical example in the Normal-normal case.关键词:...
摘要: With a fixed equivalence criterion, formulas for assessing the possibility that a material in a complex but static stress state will pass to a limiting (critical) state are compared.关键词: complex stress state equivalence criterion limiting state critical surface convexity concavity hydrostatic ...
The frames can be analyzed for internal force, stress, and strain using the theory that has already been developed for the three types of members. Displacement analysis, when attempted through an extension of the formulas of the three member types, may become cumbersome, at least for some kind...
Two equivalent formulas for the longitudinal displacement profile in squeezing ground considering finite strain are proposed. The applicability of displacement-release coefficient by small strain analysis for quantifying the stress relief to squeezing ground is obtained....
