The quality and variety of their properties, the composite materials are widely used in naval military. The possibility of integrating smart function in materials...

Ultrasonic flow meters are commonly used in wastewater management. Under certain circumstances, a reduction in the flow meter range may occur and cause significant...

In recent years, requirements in terms of service-life of civil engineering structures have become more and more stringent, so that the focus of designers and owners...

Knowledge of early age evolutions of the concrete properties is of a great interest for predictions of cracking risks. In this period, from the time of setting,...

The determination of the stress level in in-situ concrete structures is of paramount importance for in the engineering field. CODA wave interferometry (CWI) has been...

This study demonstrated the feasibility of applying an ultrasound test to evaluate the ability of a powder to interact with a solvent and thus to predict the...

A set of predictive tools to diagnosis reconstitution and ageing behaviour of dairy powders

Fuel cells are a promising alternative to classical fossil energy based engines used in transport applications and electro-generators. However, there still exist...

Infrastructure is subject to continuous ageing. This has given life cycle management of infrastructure an increasingly important role. Reliable inspection and...

Acoustic streaming, i.e. the flow induced by a propagating acoustic wave, is investigated here with both experiental and numerical approaches. The ultrasound source is...

Environmental and operational conditions cause corrosions and fatigue damage in cables used in civil engineering. For their non-destructive testing, an appropriate...

L'interaction des ondes guidées dans un cylindre avec des endommagements nonaxisymétriques est étudiée. Une méthode hybride en trois dimensions est développée...

This chapter describes non-destructive test methods based on surface guided mechanical waves for application to concrete. After a summary of the history of development...

This chapter describes the impact echo non-destructive test method. After a summary of the history of the development of the method, the basic physical phenomena...

Ultrasonography is an established technique to follow up injured tendons, although the lesions' echogenicity tends to become normal before the tendon is ready to...

La présente invention concerne le domaine de la détection et l’analyse de microporosités dans des matériaux comportant plusieurs phases, dont au moins une première...
