✦ Synopsis
Two versions of finite strip method (FSM) namely semi-analytical and spline methods are developed to calculate the stability and instability regions in the case of flat and curved thin-walled composite laminated structures under harmonic axial in-plane loads in the context of so-called parametric loading. The strain terms are expressed in terms of the Koiter-Sanders theory of shallow shells. In order to demonstrate the capabilities of the developed methods in predicting parametric behavior of the subject structures, some representing results are obtained and compared with those in the literature. Good accuracy in the results is achieved.
