Tīmeklis2024. gada 7. jūl. · $\begingroup$ I do not wish to be pedant here, but many mesh-based method can be Lagrangian or particle based method can sometimes be Eulerian. As @Paul mentioned, it is solely the frame of reference in which the equations are solved. For instance, for rotating domains in CFD, we often do rotating …
Lagrangian vs eulerian strain
Did you know?
TīmeklisThis gives a true strain result that is in the initial reference orientation, like a Green strain tensor. The result is a bit of a hybrid because it is based on \({\bf D}\), which is clearly an Eulerian quantity, but it is in the reference orientation, like a … TīmeklisThe Green strain tensor: E = 1 2(FT ⋅ F − I) is. E = [0.515 0.081 1.010 0.081 0.123 0.000 1.010 0.000 0.781] which is different still from both the small strain tensor, ϵ, and U − I. But while ϵ will change with rotation, at least E does not. This is due to the quadratic terms in E.

The formulation and the results emphasize the similarities in form of the Eulerian and Lagrangian stresses conjugate to the strains f(V) and f(U), respectively. Many of the results involve the solution to the equation AX −XA = Y, which is presented in a succinct format. 1. Introduction
