WebIntroduction This page begins a series on the many strain definitions that exist and are used throughout mechanics. We will start here with so-called infinitesimal strains.This is a bit of a misnomer because, as we will see, it is actually rotations that need to be small, not the strains themselves, in order to accurately use the small strain equations. WebEquation (5.56.31) states that the left Cauchy-Green tensor is objective (frame-independent). We note that it can be easily proved that the inverse of an objective tensor …
