| Abstract: | Based on the principle of stationary complementary energy applied to free vibration of an elastic body, equations which control the body's stress modes of free vibration are derived and a new approach (stress approach) for vibration mode analysis of elastic systems is suggested. Two examples (plane truss and simply supported rectangular plate) are given to show the effectiveness of the approach. |
