Stress strain and youngs modulus

Click For Summary
SUMMARY

The discussion confirms that the equation for plotting a stress versus strain graph in the elastic region is correctly represented by the formula stress = strain * Young's modulus. The variables are defined as follows: stress (F/A) is the force per unit area, strain (dL/L) is the change in length divided by the original length, and Young's modulus serves as the proportionality constant. This relationship holds true within the elastic limit of materials.

PREREQUISITES
  • Understanding of stress and strain concepts in materials science.
  • Familiarity with Young's modulus and its significance in elasticity.
  • Basic knowledge of linear equations and graph plotting.
  • Concept of the elastic limit in material behavior.
NEXT STEPS
  • Study the derivation of Young's modulus in detail.
  • Explore the elastic limit and its implications in material selection.
  • Learn about different materials and their stress-strain curves.
  • Investigate the applications of Young's modulus in engineering design.
USEFUL FOR

Students and professionals in materials science, mechanical engineering, and civil engineering who are interested in understanding the mechanical properties of materials and their behavior under stress.

When plotting a stress against strain graph is this the right equation that fits the form y=mx+c?
I got (F/A)=y(dL/L) where F is force A is area y is youngs modulus dL is change in length and L is original length. The Y is F/A. The m is y and x is dL/l (in y=mx) is this correct? Thank you

Looks correct to me.
 
The answer is yes, if you are within the elastic region.
 
stress = strain * Young's modulus in the elastic region so that looks correct.
