Abstract: We study the effect of a dimplelike geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling, and ...

Abstract: In the original publication, the finite element model (Sec. 3.2) had a width W of 20 mm while it should have been 25 mm. Based on the corrected analysis, Fig. 10 (page 7) and Fig. 13 (page 8) should be updated as follows.

Abstract: We present a combined experimental and analytical approach to study the formation of creases in tightly folded Kapton polyimide films. In the experiments, we have developed a robust procedure to create creases with repeatable ...
