Description
Tyler Felgenhauer, Satchi Venkataraman, and Ethan Mullen study fire ant nests in a paper from twenty twenty-four. Ant nests under soil are full of pores and chambers. The team asked why these weak looking structures resist collapse so well.
They scanned metal casts of real nests and built computer models of the soil and pores. They then pressed small blocks of the model under confined load and watched where stress and damage went. The nests proved layered by depth. Top parts spread damage and soak up energy like a shield. Lower chambers focus stress in one place. The authors say this layered design explains much of the strength.
