SUMMARY

Juan Carlos Pina is an Associate Professor in Structural Engineering at the Department of Civil Engineering, University of Santiago, Chile.
He studied Civil Engineering at the Universidad Nacional de Cuyo in Mendoza, Argentina, graduating In March 2005 with a major in structural engineering. Between December 2004 and July 2005 he was employed at Camps & Partners as a Junior Structural Engineering. From July 2005 to September 2007 he worked at Industrias Metallúrgicas Pescarmona S.A. as a Mechanical/Structural Design Engineering. During this period he was involved in the design of hydro-mechanical equipment for hydroelectric power plants. In October 2007, Juan Carlos went to the University of Swansea in Wales, for a Master degree in Computer Modelling and Finite Elements in Engineering Mechanics. In 2009, he graduated with Distinction within the Civil and Computational Engineering Centre with the thesis entitled “Yield strength of porous material – A multi-scale approach”, under the supervision of prof. E.A. de Souza Neto. After graduating, he started a PhD at the Eindhoven University of Technology in the Mechanics of Materials group under the supervision of prof.dr.ir. M.G.D. Geers and dr.ir. V.G. Kouznetsova. He obtained his PhD in May 2015 with a PhD thesis entitled “Elevated temperature thermo-mechanical behaviour of cast irons: a numerical-experimental investigation”. The work combined the use of numerical and experimental tools to study the thermo-mechanical response of cast irons for temperatures ranging from room temperature up to 500 ºC. Between June 2013 and August 2013 we worked as a Mechanical Analyst at ASML, one of the world’s leading manufacturers of chip-making equipment and a key supplier to the chip industry.
His current research interests include: computational mechanics of solids and structures, mechanical and thermo-mechanical response of materials with complex microstructures, multiscale mechanics, micromechanics, plasticity and viscoplasticity for small and large deformations.
