This study aims to investigate the Bi-Stability phenomenon in cylindrical fiber reinforced laminated composite shells. The origin of Bi-Stability behavior could be found in particular anti-symmetric layup sequence and fibers orientation. First, the kinematic and constitutive equations are derived, based on Classical Laminate Plate Theory (CLPT). Afterwards, the layup sequence and the way it leads to bending and twisting decoupling would be described. The Bi-Stability will be explained due to existence of one local minimum of strain energy, which indicates the second stable state of the plate. Analytical equations are introduced in order to calculate the cylindrical shell's total strain energy under pure bending and the second stable state geometry and characteristics are derived from the strain energy plots and the local strain energy minimum position, which is depicted in the plots. Furthermore, a finite element simulation will be performed in order to verify the presented theory to explain Bi-Stability phenomenon.
