“…A very important characteristic is the type of data being collected, such as acceleration, strain, tilt, impedance (Overly et al 2008), temperature (Harms et al 2009b), and others (Perez, et al 2010;Lynch and Loh 2006), including fiber optic sensors , Chang et al 2001. One example of particularly intensive sensing is that of the new I35 bridge in Minneapolis, Minnesota, which was built to replace the I35 bridge that collapsed in (French et al 2011.…”

“…Moreover, SHM implements sensors and actuators, smart materials, data transmission and computer-software potentials alongside the structure in order to detect, localize, quantify and assess the damage that can affect the collapse of the structure at a given moment or over time [ 2 , 3 ]. With applications in civil engineering [ 4 , 5 , 6 , 7 ], the aerospace industry [ 8 , 9 , 10 , 11 , 12 ], mechanical engineering [ 13 , 14 ] and the naval industry [ 15 , 16 , 17 ], SHM represents an interdisciplinary scientific field.…”

This paper presents the application of a hybrid approach for damage localization in concrete plates of arbitrary geometric shapes and a constant thickness. The hybrid algorithm utilizes fast discrete wavelet transformation, energy approach and time of flight criteria for the purpose of the localization of single- and multi-damage problems inside or on the periphery of concrete plates. A brief theoretical background of the hybrid method as well as numerical procedures for modeling the piezoelectric smart aggregate and ultrasonic wave propagation are presented. Experimental and numerical verification of the damage localization were performed on square samples/models with one or two damages and with 16 positions of piezoelectric smart actuator/sensor aggregates. After the verification of the hybrid method, a numerical simulation was performed on models with one or two damages for plates of arbitrary geometric shapes. Based on the obtained results, it was concluded that the proposed method can be applied to damage localization in concrete plates of arbitrary geometric shapes. The presented method and numerical procedure can be further used in research through varying the geometry, number and position of damages as well as the number and position of piezoelectric smart aggregates.

“…Investments in technologies such as Condition Based Maintenance (CBM), Structural Health Monitoring (SHM), Prognostics and Health Management (PHM), and others are critical to both effectiveness and affordability [10]. Some of the potential benefits of such a system are better understanding of the materials, inputs for future structural designs, enhancing confidential levels, aiding decision making process of life extension programs or future sales of ships and providing monitoring capability for damage in hard to reach areas or hidden structures, thereby minimizing the need for expensive tear-down inspections.…”

Abstract-Corrosion represents one of the largest through life cost component of ships. Ship owners and operators recognize that combating corrosion significantly impacts the vessels' reliability, availability and through life costs. Primary objective of this paper is to review various inspections, monitoring systems and life cycle management with respect to corrosion control of ships and to develop the concept of "Corrosion Health" (CH) which would quantify the extent of corrosion at any point of ships' operational life. A system approach in which the ship structure is considered as a corrosion system and divided into several corrosion zones, with distinct characteristics, is presented. Various corrosion assessment criteria for assessment of corrosion condition are listed. A CH rating system for representation of complex corrosion condition with a numeric number along with recommendations for repair/maintenance action is also discussed.Index Terms-Corrosion control of ships, corrosion health, corrosion of ship structure, marine corrosion, monitoring systems, ship inspections.
