摘要：

The dynamic instability of longitudinally stiffened panels having rectangular internal cutouts under parametric in-plane loading is studied by using a developed finite strip method (FSM). The loading is considered as uniform stresses throughout the whole area. The effects of perforations on the instability load frequency regions are investigated using the Bolotin's first order method and a negative stiffness modeling approach. In order to demonstrate the capabilities of the developed methods in predicting the structural dynamic behavior, some representing results are obtained and compared with those in the literature wherever available.
