ABSTRACT
The stress state of a point inside a deformed solid is defined by the Cauchy stress tensor, T. The expression for T, referring to the axes defined by the principal stresses (σ1, σ2, σ3), is given by Equation A3.1: https://www.w3.org/1998/Math/MathML"> T = σ 1 0 0 0 σ 2 0 0 0 σ 3 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003169659/21dba207-18a6-49a1-b5b3-c46a8d6cf2d8/content/TNF-ANNX-A_eqn_0001.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
