The Compressive Strength of Meteorites
Contributions of the Society for Research on Meteorites, 1942 ABSTRACTAltho the compressive strength of meteorites is important in relation to the detonation of meteorites in flight and probably in other connections in meteoritics, only one determination of it existed prior to this study. The compressive strength of 8 stones, ranging from 900 to 54,000 lb./in2., is reported.

The compressive strength of crumpled matter [PDF]
Nature Communications, 2019 AbstractCrumpling a sheet creates a unique, stiff and lightweight structure. Use of crumples in engineering design is limited because there are not simple, physically motivated structure-property relations available for crumpled materials; one cannot trust a crumple. On the contrary, we demonstrate that an empirical model reliably predicts the reaction
