Abstract

Fundamental vibration of a bent beam, which has one bend and is clamped at both ends, is studied in this paper by means of the energy metheod. The frequency equation is obtained in a form of the determinant of five orders, and numerical calculations are carried out for the bent angle of 0°, 45°, 90 °, 135°, 180°and for the length ratio of 1, 3/5, 1/2, 1/3, 1/7.
