Failure behaviors of C/C composite tube under lateral compression loading

Failure behaviors of C/C composite tube under lateral compression loading

Mechanical responses and failure behaviors of advanced C/C composite tube are very important for structural component design in nuclear reactor. In this study, an experimental investigation was conducted to study mechanical properties of C/C composite tube. Quasi-static compression loading was appli...
