This figure shows the stress-strain curve for a polymer. The following three questions refer to this figure

1) What do the region A, B , C, D, E and F means?

2) What type of polymer this curve represents?

Solution

from Point A to F represents elastic region + plastic region.

A - elastic point

B - yield point

F - Rupture point

This curve represents thermoplastic type polymer.

At point of Rupture it possess ultimate strength.
