How a Tensil Stress Strain Curve Is Created
I was hoping someone could help me interpreting a Stress Strain Curve.
As part of my introduction to Civil Engineering I am trying to get my head around how a stress strain curve is created, for example I have a steel sample and wish to perform a tensile test.
While the steel sample is being stretched I want to know: -
Does the force applied to the steel sample continue to increase until the steel sample elongates at which point no additional load is applied until the steel stops elongating at which point more force is applied until the steel continues to elongate?
Does the force applied to the steel sample continue to increase uniformly and the elongation measured at regular intervals?
Does this make sense?
