WebbIntroduction This page covers principal stresses and stress invariants. Everything here applies regardless of the type of stress tensor. Coordinate transformations of 2nd rank tensors were discussed on this coordinate transform page.The transform applies to any stress tensor, or strain tensor for that matter. Webbshape national security strategy, ii) to set acquisition policy, and iii) to inform critical investments in people, equipment, infrastructure, services and supplies. As sovereign debt challenges squeeze national budgets, and emerging threats disrupt traditional notions of security, this volume offers valuable tools to navigate the
