The 2016 Congress of the International Union of Theoretical and Applied Mechanics (IUTAM) was held in Montreal, Canada on August 21-26. This is a main event in mechanics held every fours years; this year the Congress was attended by approximately 2100 researchers. As is the custom, the presiding Bureau selected 3 young scientists for the Bureau Prize, based on their papers and their presentations at the Congress. To be eligible for the award, a presenter must be no older than 35 years of age at the time of the Congress, and must indicate that he/she wishes to be considered for the award. The recipient in solid mechanics was Dr. Stavros Gaitanaros, Ph.D. Engineering Mechanics, The University of Texas at Austin, 2014, presently assistant professor in civil engineering at Johns Hopkins University. The title of his paper and presentation was: “The effect of Polydispersity on the Crushing of Open-Cell Random Foams,” by Stavros Gaitanaros, Stelios Kyriakides, Andrew M. Kraynik.
