What is stress?Show answer
Stress is the internal force carried per unit of cross-sectional area:
What is strain?Show answer
Strain is how much the material deforms relative to its original size:
What is the stress-strain diagram?Show answer
Plotting stress (vertical) against strain (horizontal) for a tensile test produces the stress-strain curve. Key features in the early part of the curve:
