Abstract: Many engineering structures need stronger design and higher service life associated with savings in weight which are fulfilled by thin walled structures; but such structures undergo large deformations under transverse loads. The rectangular plates are considered as the structural element and their vibration and instability behaviors are studied under periodic transverse loads. The effect of geometric non-linearity on the natural frequencies of a rectangular plate under uniformly distributed and concentrated transverse loads are obtained. In case of dynamic stability study, the boundaries of the primary instability region become wider at higher excitation frequency. The effect of geometric non-linearity predominates and large amplitude of vibration is more dangerous than that of small amplitude.
