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 ...

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 ...

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