Which of the following is true for elastic potential energy density?
Options
(a) Energy density=1/2 x strain x stress
(b) Energy density= (strain)² x volume
(c) Energy density= strain x volume
(d) Energy density = stress x volume
Correct Answer:
Energy density=1/2 x strain x stress
Explanation:
Energy density = Work done / Volume = (1/2) x strain x stress.
