Shell structures—thin, curved elements such as cylinders, spheres and domes—are prized for their high strength-to-weight ratio but are exceptionally sensitive to buckling instabilities. Even minute ...

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

HUNTSVILLE, Alabama - NASA engineers improvised in Huntsville on Wednesday when their carefully planned - and televised - "can crush" experiment didn't crush a rocket shell as expected. But improvise ...

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 ...
