An engineer has designed a model to guide better design of thin-walled structures, like planes, cars and submersibles, to avoid catastrophe like sudden collapse due to buckling. A University of ...

Functionally graded shell structures combine spatially varying material properties with curved geometries to achieve tailored strength, stiffness and stability characteristics. These shells often ...

Engineers looked to nature to find a shape that could improve all kinds of slender structures, from building columns to bicycle spokes -- they found an answer in sea sponges. Judging by their name ...
