Elevated Temperature Progressive Damage And Failure Of Duplex Stainless Steel, Darren P. Luke
Elevated Temperature Progressive Damage And Failure Of Duplex Stainless Steel, Darren P. Luke
Civil Engineering ETDs
Ductile failure of metals has been the focus of research efforts within academia and industry for many years since it is tremendously important for understanding the failure of structures under extreme loading conditions. However, limited research has been dedicated to elevated temperature ductile failure, which is critical for evaluating catastrophic events such as industrial, structural or shipping vessel fires. A detailed investigation was conducted on the structural response of Duplex Stainless Steel at elevated temperatures. The temperature dependence of elastic modulus, yield strength, ultimate strength, and ductility was measured up to 1000°C and a continuum damage plasticity model was developed. …
