Apparatus for Measuring Strength in Biaxial Compression [PDF]
Review of Scientific Instruments, 2021 Most measurements of compressive strength of ductile materials have involved Hopkinson-Kolsky bars or Taylor anvils placing samples in uniaxial compression. In these geometries strain is limited by the tendency of the sample to petal, in analogy to necking in uniaxial tension.

The Compressive Strength of Meteorites [PDF]
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.

Effect of Granule Strength on Compressed Tablet Strength.
Chemical and Pharmaceutical Bulletin, 1995 The effect of granule strength on the strength of a tablet compressed under a certain force was examined. Crushing strength and diametral compression tests were carried out to assess granule and tablet strength, respectively. When granules were weak, tablet strength increased with granule strength.

Prediction model for compressive strength of rock-steel fiber reinforced concrete composite layer
Rock and Soil Mechanics, 2021 To study the uniaxial compressive strength calculation method of rock-steel fiber reinforced concrete (R-SFRC) composite layer, uniaxial compression test was carried out on rock, steel fiber reinforced concrete and R-SFRC composite layer specimens.

Journal of Asian Concrete Federation, 2022 The effect of raw materials on the compressive strength of concrete is a complex process, especially in the case of ultra-high-performance concrete (UHPC), where a higher number of inter-dependent parameters are involved in the strength development.

Compressive Strength Prediction of Lightweight Concrete: Machine Learning Models
Sustainability, 2022 Concrete is the most commonly used construction material. The physical properties of concrete vary with the type of concrete, such as high and ultra-high-strength concrete, fibre-reinforced concrete, polymer-modified concrete, and lightweight concrete ...

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
