RISPrecursor Damage Quantification in Composite Structures Using Coda Wave Interferometry and Nonlinear Ultrasonics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Methods to quantification of precursor damage in carbon fiber reinforced polymer (CFRP) composite structures are reported herein. These techniques include coda wave interferometry (CWI) and nonlinear ultrasonics (NLU). ...
Effect of Time-Dependent Strength Recovery of Composite Materials: Quantification Through Higher Order Ultrasonic Non-Linearity Using Lamb Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The understanding of strength recovery behavior under a dynamic loading environment provides a guidance for optimizing the design of composite structures for in-service applications. Although established for metals, the ...
