ST7-1.70.20.3 Stress Linearisation using the Peek Tool
Geometric discontinuities in structures cause stress concentrations which do not have linear distributions. It is often necessary to calculate equivalent membrane and linear bending stresses from these stress fields to perform compliance checks using design standards.
This document illustrates how to post-process 2D plane strain/stress models in Strand7 to extract the linearised membrane and bending stresses along arbitrary lines using the Peek tool. A way to extract the linearised stress is...
