Abstract
This study investigated the failure behavior of ceramic egg-shaped shells under external pressure. Four ceramic egg-shaped shells with two thicknesses were manufactured and then subjected to geometric measurements, hydrostatic pressure tests, analytical validations, and numerical simulations. The experimental results were compared with the simulation results to validate the feasibility of the numerical modeling. Furthermore, the effects of thickness and shape on ceramic egg-shaped shells were explored. The research findings indicate that ceramic egg-shaped shells have excellent compressive properties. The performance ratio of these ceramic egg-shaped shells is approximately 10 and 5 times higher than those of resin and steel egg-shaped shells, respectively. This finding highlights the crucial role that affordable ceramic materials can play in facilitating the widespread use of submersibles in deep waters.
期刊介绍：
Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants.
The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome:
• Pressure vessel engineering
• Structural integrity assessment
• Design methods
• Codes and standards
• Fabrication and welding
• Materials properties requirements
• Inspection and quality management
• Maintenance and life extension
• Ageing and environmental effects
• Life management
Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time.
International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
