복합하중상태에 있는 복합재료 원통형 쉘의 좌굴 거동

This paper deals buckling behavior of laminated composite cylindrical shells subjected to combination of axial compression and torsion. Linear and nonlinear finite element analysis are carried out. The influence of load type, load ratio, fiber orientation angle, stacking sequence, and initial imperfect on the buckling behaviour is discussed.
