Physics - Stress versus strain graphs

Stress versus strain graphs

Investigate the stress versus strain graph. Click go to start.

A graph of stress versus strain for a material looks similar to a force
versus change in length graph.

Young's modulus applies to the region of this graph up to the proportional
limit and is in fact the gradient of the graph up to this point.

Stress versus strain graphs give a comparison of stiffness [1] between two
materials, A and B, from such graphs.

A material is _brittle_ if it fractures after very little plastic
deformation [2] - the smaller the amount of plastic deformation, the more
brittle the material is.
