RISViscous Shocks in the Destabilized Kuramoto-Sivashinsky Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study stationary periodic solutions of the Kuramoto-Sivashinsky (KS) model for complex spatio-temporal dynamics in the presence of an additional linear destabilizing term. In particular, we ...
Nondestructive Bridge Deck Testing with Air-Coupled Impact-Echo and Infrared Thermography
Publisher: American Society of Civil Engineers
Abstract: Two different nondestructive test (NDT) methods, air-coupled impact-echo (IE) and infrared (IR) thermography are evaluated on a full-scale simulated reinforced concrete bridge deck containing simulated delamination and ...
Comparison of NDT Methods for Assessment of a Concrete Bridge Deck
Publisher: American Society of Civil Engineers
Abstract: The field application of three different nondestructive tests (NDTs)—air-coupled impact echo (IE), infrared (IR) thermography, and sounding (chain drag)—are evaluated in this paper, where an actual in-service concrete ...
