The visit of the PI Nina Čeh to Impact Engineering Laboratory ended on 29th of November 2019.
During the two last weeks (18 – 29 Nov) Nina Čeh and Nik Petrinić discussed the future of the collaboration and plans for joint proposals in the next year. Nik Petrinić’s visit to Faculty of Civil Engineering in Rijeka is planned for spring 2020, within which future joint research proposals will be discussed in more detail.
All the updates regarding that will be posted here.
The third series of experiments was conducted, with included “vertical” and “horizontal” experiments (which needed to be repeated). These experiments were conducted between Oct 21 and Oct 25 2019.
The DEM-based algorithm awailable to simulate rocking that is developed within this project is extended so that it includes the tangential contact. In this phase only one model for tangential contact is introduced, while other possible models can be used in the future if necessary.
The discussion about modelling the tangential contact between bodies is the starting point for initiating the collaboration on development of an in-house code for disrete element simulation that is onoging in the Impact Engineering Laboratory group.
The second series of experiments planned in the experimental program was designed and prepared. The experiments for “horizontal” collisions were conducted between Oct 9 and Oct 11 2019.
The first DEM-based algorithm available to simulate rocking of a single rectangular block on a base is developed in Matlab. The first version of the code includes only normal contact between the bodies, while tangential contact will be added later.
The normal contact is modeled as:
The first series of experiments planed in the experimental program was designed and prepared. The experiments for “vertical” collisions were conducted between Sep 10 and Sep 15 2019.
The PI Nina Ceh travelled to Impact Engineering Laboratory at the UNiversity of Oxford on the 26th of August 2019.
