TENSILE TESTING GRAPHS

TENSILE TESTING GRAPHS

1. Stress Strain Graphs

   • Strain
     • On the X-axis
   • Stress
     • • We must calculate the Sectional Area (CSA)
         • 2 types of CSA to find
           • CSA of a Rectangle
           • CSA of a Circle

2. Load Extension Graphs

3. Key Words

   • A YIELD STRENGTH or YIELD POINT is the material property defined as the stress at which a material begins to deform plastically.
   • DEFORMATION is when a material is in the process of deforming or distorting.
   • PLASTIC DEFORMATION is when a piece of properties have been changed.
   • PROPORTIONALLY when thing moves up at an even pace.
   • ULTIMATE TENSILE STRENGTH (UTS) is when a piece reaches the most tension it can take before breaking. Anymore tension and it will break.
   • FRACTURE to break.

4. 0.1% Proof Stress

   • Load Extension
   • Stress Strain
   • Is to find the Yield Point on the graph when it isnt clear to see

5. Youngs Modules of Elasticity

6. Ultimate Tensile Strength
