I'm currently doing a project in my materials class and I wanted to check if these two material indices were right. The objectives are:
1. The material must not fracture
2. The material must be strong (no deformations)
Material Index 1
------------------------
Considering a yield-before-break scenario
Material Index = [tex]\frac{K_{1c}}{\sigma_{y}}[/tex]
where K1c is the fracture toughness and sigma y is the yield strengthAnd for the plot would I put [tex]{K_{1c}}[/tex] on the y-axis [tex]{\sigma_{y}}[/tex] on the x axis, and pick the material near the upper right corner?
Material Index 2
-------------------------
I want a really strong material that doesn't deform easily so is the material index this:
Material Index = [tex]E{\sigma_{y}[/tex]
Here E is Young's Modulus and Sigma y is the yield strength. Also, how would you plot this?
