"Continuum mechanics is a branch of mechanics that deals with the deformation of and transmission of forces through materials modeled as a continuous mass rather than as discrete particles. The French mathematician Augustin-Louis Cauchy was the first to formulate such models in the 19th century. A continuum model assumes that the substance of the object completely fills the space it occupi… " - Continuummechanics.org

But while ϵ will change with rotation, at least E does not. This is due to the quadratic terms in E. WebApr 17, 2024 · The strain tensor does not have to be positive definite, as mentioned before. On the other hand, you are asking what type of strain tensor are positive definite. A positive tensor would have positive principal strains.
