In the COMPMECH group at the University of Pavia, in collaboration with foamLab (University of Naples Federico II) and with the valuable support of LiTeM – Life Testing
Machines, we are working to advance current knowledge on the high-cycle fatigue behavior of closed-cell elastomeric foams. These materials are increasingly becoming
game-changers in modern running shoes. Here is an example of one of the tests we are conducting using a LiTeM BYC 200 machine: the foam specimen is subjected to 200,000 loading cycles with a
maximum compressive Hencky strain of 1.4.
Thanks to in-house–developed codes, we are able to measure absorbed energy, released energy, residual strain, and many other relevant parameters.
Feel free to reach out if you would like to know more!

This project is the result of the combined expertise of Paolo Iaccarino, Ferdinando Auricchio, Simone Morganti, and Ernesto Di Maio, with the essential technical support of Fabio Mattiauda and the LiTeM team.
