Class 11 Physics simulations · Mechanical Properties of Solids

Stress–strain curve

Load a wire and trace it through its elastic and plastic regions.

Open the simulation

What to notice

The straight elastic region ends at the yield point, after which the wire deforms permanently.

Key relation

Y = stress / strain

Try this

Load just past the yield point and back off.

What you can change

• Applied load: 0 to 100 %
