Development of a finite strip method for efficient prediction of buckling and post-buckling in composite laminates containing a cutout with/without stiffener

One of the main methods for improving the strength of the notched laminates, which are commonly used in the engineering structures, is to employ a stringer in a proper configuration. To optimize the design of these perforated laminates under compression loading, accurate characterization of the effects of various parameters on the instability behavior plays a significant role. For this purpose, after a review on the main previous researches, a...
