BIOSKETCH: “
Juan Carlos Nieto Fuentes was born in 1985, in Gijón (Spain). He earned a 4 year BEng. degree in Mechanical Engineering from the JC_foto
University of Oviedo (Spain) in 2015. He 
carried out his bachelor thesis in the University of Bologna (Italy), where he had the opportunity to study the uni-axial and flexural behaviour of fibre reinforced concrete elements, under the supervision of Prof. Nicola Buratti (Italy) and Prof. María Jesús Lamela (Spain). Immediately after graduation he started working in Tuinsa Norte, a metal company, where he is currently in charge of the design and analysis of steel structures. 

              Simultaneously, he started a MEng. degree in Structural Integrity and Durabilility of Materials, Components and Structures from the University of Oviedo, which provided to him specialized training on the analysis of the behaviour of industrial components, from sizing and calculation to the selection of the appropriate materials. He developed his master thesis as a research project in collaboration with an industrial partner and supervised by Prof. Inés Peñuelas and Prof. Emilio Martínez (both from Spain). He studied the effect of thermo-mechanical damage in a steel tool used in the aluminium alloy
process, evaluating the influence of the properties of different materials on the plastic deformation and redesigning the structural component.”

MONTHLY REPORT

20/12/2016:

“Although there was some delay with the bureaucratic paperwork, I finally arrived in Israel in December 2016. Since my arrival, at Ben Gurion airport in Tel-Aviv, I have swiftly realized that the Israeli citizen is prone to help the non-native. In that sense, everything that you need to ask feel free to do it since almost everybody speaks English – even though the native languages are Hebrew and Arab.

My place of work is the Technion – Israel Institute of Technology, which is the oldest university in the country. Namely, within Technion, I develop my research in the Material Mechanics Laboratory. There are several facilities available in the lab, such as: mechanical testing, microstructural characterization (optical, SEM and TEM), dynamic loading apparatus, high speed imaging (200.000 fps), powerful computers for FEM calculations and much more. I remember the first computer that I turned on: 32 CPUs and 64 Gb RAM memory…impressive! Currently, regarding the project, I am trying to understand the physics of the problem by means of book reading and literature review. Moreover, I am taking some courses in parallel to strengthen the knowledge in such a field.

Regarding the city where I live, Haifa, is the third largest city in Israel. It was built in the heart of Mount Carmel, and due to this fact moving on foot could be a big issue – you must be on shape. On the other hand, summer lovers can find in Haifa 17 km of beaches along its coast. Furthermore, the extensive vegetation of the area makes you breathe fresh and healthy air. People here are so kind and helpful and some of them speak Spanish, making the communication even easier if possible.
In conclusion, things cannot be better up to now.”

During the last five months, since my arrival to Israel, I have been working on a material constitutive model based on dislocation mechanics.

The aim of this model is to characterize the work hardening of ductile materials under high strain rate loading. Different microstructural aspects of the problem are considered, such as the evolution of dislocations from a uniform arrangement to an organized one, where dislocation cells are formed. Throughout the cell formation, manifold expressions based on the model developed by Estrin-Tóth-Molinari-Bréchet (ETMB) to mimic the generation, migration and annihilation of dislocations in both cell interiors and walls are taken into account.

Up to this time, I am trying to fit the previously mentioned expressions in order to reproduce the stress-strain curve of Copper under high strain rate conditions, comparing the analytical results with experimental ones.

Regarding social life, whenever I get the chance I join one of the several trips all over the country that the Technion offers by means of its International School. This association is very active and promotes lots of activities for both undergraduate and graduate students. Moreover, with the student card I am entitled to a discount if I want to go to museums or theatres throughout Israel. In summary, the country offers a plethora of places to visit: the multi-cultural Jerusalem, the cosmopolitan Tel-Aviv, the old city of Acre, Nazareth (the Arab capital of Israel), the lowest point on the Earth surface, etc.

The next stop will take place in Madrid, 22nd June 2017, where the OUTCOME  project is organizing an industrial workshop in which many lecturers will explain different structural issues encountered in aerospace and defense applications.
