A universal ultrasonic apparatus for measuring elastic constants of materials / Abdelmalek Bouhadjera

Public ISBD Titre : A universal ultrasonic apparatus for measuring elastic constants of materials Type de document : texte imprimé Auteurs : Abdelmalek Bouhadjera, Auteur ; D. Waller, Directeur de thèse Editeur : Nottingham : [s.n.] Année de publication : 1988 Importance : 212 f. Présentation : ill. Format : 30 cm. Note générale : PhD Thesis : Physics : University of Nottingham : 1988 Bibliogr. f. 186 - 191 Langues : Anglais (eng) Mots-clés : Ultrasonic Measuring Elastic  constants Index. décimale : D000488 Résumé : An ultrasonic apparatus for measuring the elastic moduli of materials was designed . The difficulty in measuring shear-wave velocity using ultrasund was overcome by a transducer cell (patent application). Thus, both compressional and shear wave velocities can be measured in a relatively simple manner. All the modules of the ultrasonic apparatus are of original design, and no off-the-shelf equipment was used. The modules include: transducer holders, amplifiers, a frequency synthesizer and a computer interface. The instrument represents a significant advance in the method of ultrasonic material testing and appears to have great market potential.
