Abstract: We investigate the use of phased array ultrasonic testing (PAUT) as an offsite non-destructive quality assurance technique for parts made by selective laser melting (SLM). SLM is a popular additive manufacturing (AM) ...

Abstract: Wave dispersion in a string carrying periodically distributed masses is investigated analytically and experimentally. The effect of the string's geometric nonlinearity on its wave propagation characteristics is analyzed ...

Abstract: The discussion article [1] written by Professor Brian Mace provides complementary analysis of several aspects of the dynamics of phononic materials and structures and an insightful perspective on some of the intriguing ...

Abstract: The study of phononic materials and structures is an emerging discipline that lies at the crossroads of vibration and acoustics engineering and condensed matter physics. Broadly speaking, a phononic medium is a material ...

Abstract: We are indeed very happy to have had the opportunity to work on this special issue and start what we hope will become an annual tradition. Special thanks to Professor Bala Balachandran for giving us the green light on this ...
