For a titanium alloy fatigue specimen under standard conditions, fully reversed bending only, using stress-strain life method find a and b for n_e = 10,000,000.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
