Brown University engineers Haneesh Kesari and Michael Monn have been studying sea sponges in order to understand how these fairly simple creatures can maintain their shape at the bottom of the ocean, despite the fact that they are subject to the constant stress of underwater waves and tidal forces. The findings of their research, published in the journal Scientific Reports showed that tiny structural rods in the sponges’ bodies have evolved the optimal shape to avoid buckling under pressure. According to the researchers, this shape could provide a blueprint for increasing the buckling resistance in all kinds of slender human-made structures, from building columns to bicycle spokes to arterial stents, as buckling is the primary mode of failure for slender structures.
The National Academies of Science, Engineering & Medicine (NASEM) recently released a report of high value for the engineering community on the "State of the Art and Practice in the Assessment of Earthquake-Induced Soil Liquefaction and Its Consequences". The report aims to help the technical community reach again consensus on issues related to liquefaction triggering assessment and build confidence in methods used to assess liquefaction initiation and its consequences.
