NettetThe linearization basis is a coordinate system that gives the X-, Y- and Z-directions to calculate the linearized stress for a selected line segment. It appears as a vector triad at the midpoint of the linearization segment. ... For 2D models, the Z-direction is normal to the plane of the model, ... NettetPrincipal Stresses — Lesson 4. In the previous lesson, we saw how the stress developed in a body is represented in the form of a second-order tensor. We have used a simple cube to illustrate how the stresses act on a small element inside a body. But we haven't talked about whether the orientation of such a cube affects the stresses acting … Nettet24. feb. 2016 · In a planar geometry, a Stress Classification Line (SCL) is obtained by reducing two opposite sides of a SCP to an infinitesimal length. SCPs are flat planes that cut through a section of a component and SCLs are straight lines that cut through a section of a component. SCLs are surfaces when viewed in an axisymmetric or planar geometry. bruce forstall
