Strength Predictions of Plates in Uniaxial Compression

Journal of the Structural Division, 1972
The prediction of the ultimate load for rectangular plates is obtained from the intersection of an elastic postbuckling loading path and a rigid-plastic unloading path. The former expresses post-buckling stability and uniqueness, affected by membrane forces and imperfections at large transverse displacements; the latter, insensitive to imperfections ...

On the uniaxial compression strength of frozen gravelly soils

Cold Regions Science and Technology, 2020
Abstract Frozen gravelly soils are often encountered in both cold regions engineering and urban underground constructions by artificial freezing method. This work takes a gravelly sand in Beijing as the basic material. Gravel grains of 10–20 mm in size are obtained and mixed with sand grains at certain ratios and then saturated frozen samples are ...

Predicting Uniaxial Compressive Strength From Log Parameters

Proceedings of SPE Annual Technical Conference and Exhibition, 1986
ABSTRACT Models for prediction of in-situ rock behaviour often suffer from lack of relevant input data, especially rock strength data. Rock mechanical testing of cores provides only discrete data points. This paper presents a method which produces a continuous plot of uniaxial compressive strength.

Uniaxial Compressive Strengths of Artificial Freshwater Ice

Advanced Materials Research, 2011
The uniaxial compression test was performed on artificial freshwater ice with a precise control-temperature unit compression tester of ice under -5, -10, -15, -20 and-30°C temperatures and strain rates ranging from 10-8 to 10-2 s-1. The loading direction was parallel to ice surface. The results showed that the compressive strength was very sensitive to

Size Effect of Uniaxial Compressive Strength of Limestone

Applied Mechanics and Materials, 2012
Using the MTS testing machine, the uniaxial compressive test of varisized da-qing limestones were undertaken, and the effect of dimensions about compressive strength, peak strain, elastic modulus and destructional forms of rock specimens were studied.

Cube tests and the uniaxial compressive strength of concrete

Magazine of Concrete Research, 1965
Summary The cube is undoubtedly the most convenient specimen to use when large numbers of crushing tests are required for concrete control purposes. The cylinder, or prism, on the other hand can give a much better estimate of the uniaxial compressive strength of concrete.

Uniaxial compressive and undrained shear strength of soil [PDF]

Proceedings of 10th Symposium on Doctoral Studies in Civil Engineering
Uniaxial compressive strength and undrained shear strength are among the most important soil parameters in geotechnical engineering. The unconsolidated undrained triaxial test and the falling cone test determine them. The uniaxial compressive strength of soil is the maximum compressive stress that the soil can withstand before failure in drained ...

Estimating the uniaxial compressive strength of a volcanic bimrock

International Journal of Rock Mechanics and Mining Sciences, 2006
Abstract Preparation of the standard sized cores from geological mixtures or fragmented rocks such as melanges, fault rocks, coarse pyroclastic rocks, breccias and sheared serpentinites is often extremely difficult. Therefore, determination of the mechanical parameters such as cohesion, friction angle and UCS is extraordinarily difficult for these ...

The Influence of Temperature on the Uniaxial Compressive Strength of Rocks

Juniorstav 2024: Proceedings 26th International Scientific Conference Of Civil Engineering
This study focuses on determination of the temperature effect on uniaxial compressive strength of different rock types. For our laboratory tests, we chose local greywacke from the Kobeřice quarry which is situated 10 km south of Prostějov. For comparison, datasets representing other rock types have been gathered from the literature cited.
