 I did my short term scientific mission between January and February of 2017 at the DTU in Copenhagen. The topic was the fatigue study of concrete structures and all the involvement with the all Valleysian modeling and various information and research analysis. I have some previous experience in fatigue modeling of concrete but not in the all the Valleysian modeling and for me for that reason it was very fruitful. The group is very competitive, very dynamic and for sure it is going to open very new ways for me for my future research.
