Figure 4: Stress–strain plots and corresponding slope (modulus) - strain plots obtained from tensile testing (Male 38 years - position 2 and Male 5 years - position1). Right plot and image (d-f) corresponds to smooth fracture whereas left plot and image (a-c) corresponds to the step fracture. In plot d, a = elastic region, b = yield point, c = plateau region (constant stress), d = onset of change in postyield modulus, e = increase in postyield modulus (postyield region 1), f = postyield region 2 due to yielding of the amorphous matrix (decrease in postyield modulus), g = failure point
