Abstract
This thesis is about the investigation of the geometrically nonlinear responses and bulging factors of cracked laminated composite cylindrical shell structures subjected to internal pressure. Hybrid strain based three-node flat triangular shell elements, developed by To and Wang were used.
Effects of dynamic responses of various numbers of layers and their angle arrangements of cracked cylindrical shell structures clamped at both ends are analyzed and studied. Bulging factors based on the concept of equivalent Young’s modulus of elasticity are found and compared with single and multiple layer composite cylindrical shell structures.
Finally, bulging factors for similar laminated composite cylindrical shells with free-free boundary conditions are also presented in this thesis.
