THE BUCKLING OF VARIABLESTIFFNESS COMPOSITE PANELS WITH
 CURVILINEAR FIBER FORMAT

Abstract

Abstract:

This paper presents a study on the concept of variablestiffness with curvilinear fiber format. Based on that concept, the redistribution of stress field occurs, which improves the buckling load of the laminated composite panels. By using ABAQUSTM, it proves the model of the concept and shows that the increment of the buckling load is significant, which is 14%.

Key words: composite material, laminated plate, buckling; , curvilinear fiber, variable stiffness, loading inplane loading in plane.
