1. It's skull and shell structure is similar to " Polysternon ". 2. One of their main characteristics is the presence of intersected crossed platy shell structure . 3. "' Binishells "'are reinforced concrete thin-shell structures that are lifted and shaped by air pressure. 4. This gives the atom a shell structure , in which each shell corresponds to a Bohr orbit. 5. The work of Budiansky and Hutchinson characterized and quantified the buckling imperfection-sensitivity of important shell structures . 6. The architect Richard Buckminster Fuller is famous for designing strong thin-shell structures known as geodesic domes. 7. In 2002 the Amphitheater was renovated by replacing the wooden shell structure with a concrete structure. 8. The shell structure consists of three layers. 9. After his thesis work, Hutchinson collaborated extensively for several years with Budiansky on the buckling of shell structures . 10. Some evolution of the shell structure observed in stable nuclei is expected away from the valley of stability.
