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? Stress Strain 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..
