1- In the diagram below identify or answer the following, using terminology and descriptions from the lecture a) What does the value of the dashed horizontal line labeled\"\" represent? b) What does the value of the dashed horizontal line labeled 2\" represent? c What happens at point3\" d) What happens in region \"4\" (between the two vertical dashed lines)? e) What happens in region \"S\" (between the two vertical dashed lines)? Stress Strain

Solution

a) 1 represents the ultimate stress.

b) 2 represents yield stress as it is lined from the yield point.

c) At point 3 material fails by fracturing.

d) It is strain hardening region which means stress increases as plastic strain increases.

e) It is strain softening region. Here specimen begins to neck.
