Damage detection sensitivity characterization of acousto-ultrasound-based structural health monitoring techniques

Autor: Fu-Kuo Chang, Vishnuvardhan Janapati, Fotis Kopsaftopoulos, Frank Li, Sang Jun Lee

Publikováno v: Structural Health Monitoring. 15:143-161

Reliability quantification is a critical and necessary process for the evaluation and assessment of any inspection technology that may be classified either as a nondestructive evaluation or structural health monitoring technique. Based on the sensiti

Challenges in Meeting the Framework for SHM System Certification and Compliance

Autor: Irene Li, Roy Ikegami, Fu-Kuo Chang, Amrita Kumar, Vishnuvardhan Janapati, Howard Chung, Taru Singhal

Publikováno v: Structural Health Monitoring 2017.

Monitoring the continued health of aircraft subsystems and identifying problems before they affect airworthiness has been a long-term goal of the aviation industry. Towards this end, Structural Health Monitoring (SHM) systems that could be used for t

A novel physics-based temperature compensation model for structural health monitoring using ultrasonic guided waves

Autor: Fu-Kuo Chang, K. Lonkar, Vishnuvardhan Janapati, Surajit Roy

Publikováno v: Structural Health Monitoring. 13:321-342

This article investigates the role of ambient temperature in causing changes to the structural wave propagation, as sensed by piezoelectric transducers, in a newer perspective. A novel approach is proposed to compensate the influence of temperature o

Damage Characterization and Classification for Composite Honeycomb Structures

Autor: Vishnuvardhan Janapati, Roy Ikegami, F. Li, W. Milan, Amrita Kumar, C. Cheung

Publikováno v: Structural Health Monitoring 2015.

Advanced composite materials are increasingly being adopted for applications in airframe structures due to their high stiffness-to-weight and strength-to-weight ratios as compared to metallic materials. However, advanced composites are susceptible to

Real-time prediction of impact-induced damage for composite structures based on failure analysis and efficient database methods

Autor: Fu-Kuo Chang, Surajit Roy, Ingolf Mueller, Vishnuvardhan Janapati, Samik Das

Publikováno v: SPIE Proceedings.

This contribution presents a novel strategy to achieve real-time prediction of non-penetrating impact-induced damage, especially delamination between plies of composite laminated structures. The proposed strategy aims to create an optimum-sized datab

Publikováno v: 53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference20th AIAA/ASME/AHS Adaptive Structures Conference14th AIAA.

This paper presents a novel model-assisted integrated diagnostics for structural health monitoring. Acousto-ultrasonic Lamb waves are propagated through a structure induced and sensed by an active piezoelectric sensor network. The damage is detected
