查询词典 bracket

The major works in this thesis are: The effect of the straight and skew cracks on the vibration properties are studied for the cantilever beam, clamped-clamped rectangular plate, simple-supported rectangular plate and triangular plate. The effect on the natural frequency and vibration mode shapes of the bracket in the presence of cracks is discussed Based on the available index of crack diagnosis, a new index, is proposed.
