Talk:Stress–strain curve/to do

There are no active tasks for this page

• Usually there is a change in slope when passing from Elastic to Plastic region, and this is the sign that we passed the Elastic region. (Please correct)
• Add different measurements of stress strain
• Precise definitions needed, such as:

  elastic limit,

  proportional limit,

  yield,

  luders strains,

  uniform elongation,

  necking

• Considere's criterion for instability?
• Better links between Yield (engineering), Stress (physics), Tensile stress, etc
• Expand brittle materials section
• yield curves of polymers and elastomers
• brittle/ductile transitions? Maybe not
• Non tension - torsion, bending, etc?
• Need some references (see Materials by Callister)
• Where is the "figure 2" spoken of in the text?
