Dynamic Mechanical Behaviour of Materials

TIME: February 13, 2017

PRESENTER: Juan Pablo Escobedo-Diaz, UNSW Canberra

LOCATION: 4F, Building 2

TYPE: Seminar


Advents in advanced materials processing, such as additive manufacturing, are producing promising novel materials that are of interest to the aerospace, defence and energy sectors. These new materials require rigorous mechanical testing at the extreme conditions of stress, strain rate, and temperature that mimic the operating conditions of the intended applications. To tackle the challenge of assessing the suitability of materials to be used in the most stringent applications, the Impact Dynamics Research Group (IDRG) at UNSW Canberra was officially initiated in 2012 of which Dr. J. Pablo  Escobedo.  The IDRG has established a unique laboratory in Australia in which is possible to assess the mechanical response of materials over a wide range of strain rates (10-1 - 107 1/s) and temperatures (up to ~900oC). The laboratory houses an instrumented Intron drop tower for low velocity impact experiments, a split Hopkinson pressure bar (tension and compression) for high strain rate testing, and a premier single/double stage light gas gun, capable of launching projectiles at velocities up to 4.5 km/s (https://youtu.be/mp0w24s0aEI).


In this seminar, Dr. JP Escobedo will present his work on previous and current research projects that will include investigations on: (a) the dynamic damage behaviour in materials, (b) the dynamic deformation mechanisms of closed-cell metallic aluminium foams; (c) the mechanical response of brain tissue simulant subjected to low-velocity impact; and (d) the dynamic mechanical response of additively manufactured Ti and steel materials


Dr. Juan Pablo Escobedo-Diaz. Obtained his PhD in Mechanical Engineering from Washington State University. Before joining UNSW in Aug 2013, he worked at three DOE-funded labs in the US: Los Alamos National Laboratory (2010-2013), the Institute for Shock Physics (2008-2010) and Lawrence Livermore National Laboratory (2005). The primary aim of his research is the development and testing of structural materials that have the potential to display superior thermal and mechanical properties when subjected to stringent environmental conditions found in aerospace, civil, industrial and military applications
