Advances in Mechanics : Selected Contributions to the 15th International Moroccan Congress of Mechanics, May 24-27, 2022, CMM 2022, Casablanca, Morocco

TheMoroccan Congress ofMechanics is a scientific event held every two years during the April–May period, initiated by the Moroccan Society ofMechanical Sciences (SMSM). SMSM is an academic society that brings together Moroccan researchers and their foreign colleagues working in the field of mechanical sciences. The 15th edition of this congress—CMM 2022—was held from May 24–27, 2022, at Hassan II University in Casablanca, Morocco, and was organized by the SMSM and the Faculty of Sciences Ain Chok of Hassan II University in collaboration with the France-Maghreb Association of Mechanics and Materials (AF3M).TheMoroccan Congress ofMechanics is a scientific event held every two years during the April–May period, initiated by the Moroccan Society ofMechanical Sciences (SMSM).
