For the phenol-formaldehyde (Bakelite) polymer, whose stress strain behavior may be observed in the ?oTensile Tests?? module of Virtual Materials Science and Engineering (VMSE), determine the following:
(a) The tensile strength, and
(b) The approximate ductility, in percent elongation.
How do these values compare with those for the phenol-formaldehyde material presented in Table15.1?
