...Austin Yunker; Rami Lake; Rajkumar Kettimuthu; Zachary Kral Aircraft structures are required to have a high level of quality to satisfy their need for light weight, efficient flight, and withstanding high loads over their lifespan. These aerostructures are typically made from a composite material...

...Ashish Kumar Singh; Vincent B. C. Tan; Tong Earn Tay; Heow Pueh Lee This paper begins with a numerical study based on earlier experiments of nonlinear vibro-ultrasonic behavior of a composite laminate with a delamination defect upon sinusoidal linear sweep signal excitation. A methodology to model...

...Shweta Dabetwar; Stephen Ekwaro-Osire; João Paulo Dias Composite materials can be modified according to the requirements of applications, and hence, their applications are increasing significantly with time. Due to the complex nature of the aging of composites, it is equally challenging...

...Mohammadreza Bahadori; Emine Tekerek; Melvin Mathew; Mazur Krzysztof; Brian Wisner; Antonios Kontsos A novel failure model updating methodology is presented in this paper for composite materials. The innovation in the approach presented is found in both the experimental and computational methods...

...John T. Welter; Daniel M. Sparkman; John C. Aldrin; David Zainey; Tyler Lesthaeghe; Vicki Kramb Characterization of barely visible impact damage (BVID) in polymer matrix composites (PMCs) is necessary to use slow crack growth damage tolerance models and evaluate remaining life of PMC components...

...Robin James; Mohammad Faisal Haider; Victor Giurgiutiu; David Lilienthal The manufacturing process of carbon fiber reinforced polymer (CFRP) composite structures can introduce many characteristic defects and flaws such as fiber misorientation, fiber waviness, and wrinkling. Therefore, it becomes...

...Simone Boccardi; Natalino D. Boffa; Giovanni M. Carlomagno; Carosena Meola; Fabrizio Ricci; Pietro Russo; Giorgio Simeoli Composite materials are becoming ever more popular in an increasing number of applications. This because of their many advantages, amongst others the possibility to create a new...
