Abstract

The failure of steel cylindrical shells with carbon fiber‐reinforced polymers (CFRP) under hydrostatic pressure is studied in this article by experimental tests and the finite element method. Simulations were performed for 12 cylindrical shells with different dent numbers, dent depths, and two perfect models with and without CFRP. The finite element models are built to simulate the buckling behavior. The nonlinear stabilization method is preferred to simulate the buckling behavior. The finite element results agree well with the corresponding experimental tests and theories. A parametric study is conducted, and the number, depth, width of dents, and the effects of CFRPs on the critical buckling pressure are discussed. The dents are placed symmetrically around the cylinder with a thickness of tc (thickness of cylinder) and 2tc mm. The initial and overall buckling load decreased with increasing amplitude for dent numbers with different dent depths on all models. The results show that the number and depth of dents generally have a negative effect on the buckling strength, while CFRPs increase the critical buckling strength and are effective in repair as a retrofitting concept.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
