Identifying Tensile and Compressive Stress in Principal Stress Extraction

Click For Summary

Discussion Overview

The discussion revolves around the identification and differentiation of tensile and compressive stress when extracting principal stress components in materials. It includes theoretical aspects of stress classification.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant inquires about how to differentiate tensile and compressive stress in principal stress extraction.
  • Another participant asserts that tensile stress is represented by positive values, while compressive stress is represented by negative values.
  • A subsequent participant questions whether having both positive and negative components follows the same classification of tensile as positive and compressive as negative.
  • A reply confirms that components with positive stress are indeed tensile, and those with negative stress are compressive.

Areas of Agreement / Disagreement

Participants generally agree on the classification of tensile and compressive stress based on the sign of the stress components, though some uncertainty remains regarding the implications of having multiple positive and negative components.

Contextual Notes

The discussion does not address potential limitations or assumptions regarding the definitions of tensile and compressive stress or the context in which these classifications apply.

When extracting a Principal stress for the component, how to differentiate/separate/identify the tensile and compressive stress in it?
 
Engineering news on Phys.org
You can distinguish tensile and compressive principal stress as follows. Tensile stress is positive; compressive stress is negative.
 
sorry for the ignorance,

if i get n positive components and n negative components, then it follows the same... ?as +ve tensile nad -ve compressive
 
Yes, components having positive stress have tensile stress. Components having negative stress have compressive stress.
 
thank u nvn
