About this Abstract
Meeting MS&T22: Materials Science & Technology
Symposium 50 Years of Characterizing Structural Ceramics and Glasses: Recognizing the Contributions of George Quinn
Presentation Title Advanced Proof Testing for Structural Ceramics
Author(s) Osama Jadaan, Noel Nemeth, Eric Baker
On-Site Speaker (Planned) Osama Jadaan
Abstract Scope Proof testing is used to remove weak ceramic components from a manufactured batch in turn truncating the lower end of the strength-failure probability distribution. This presentation advances the early work done on proof test theory, which was limited to simple stress states, to include more general stress and material states. The theory introduced takes into account practical conditions often encountered in industrial applications such as multiaxial transient service and proof test thermomechanical loads, non-alignment (off-axis) loading between service and proof test stress states and changing material behavior with time, for both fast fracture and time-dependent failure conditions. This advanced proof test theory was coded into the integrated design code CARES/Life (Ceramic Analysis and Reliability Evaluation of Structures/Life), which is a postprocessor to commercially available Finite Element software. Examples will be presented.
