Comparison of Mechanical Properties and Sensitivity of Compressive and Flexural Strength of Artificial Frozen Sand

open access: yesGeofluids, 2022
Some zones of freezing curtains of subway contact channels are subjected to compression and tension. Thus, understanding the mechanical properties and relationship between the compressive and flexural strengths of frozen soil is crucial.

Structural response of concrete-filled elliptical steel hollow sections under eccentric compression [PDF]

open access: yes, 2012
The purpose of this research is to examine the behaviour of elliptical concrete-filled steel tubular stub columns under a combination of axial force and bending moment. Most of the research carried out to date involving concrete-filled steel sections has

An ensemble tree-based machine learning model for predicting the uniaxial compressive strength of travertine rocks

open access: yes, 2020
Estimating the uniaxial compressive strength (UCS) of travertine rocks with an indirect modeling approach and machine learning algorithms is useful as models can reduce the cost and time required to obtain accurate measurements of UCS, which is important

Inversion analysis of M-C criterion parameters of rock based on uniaxial shearing failure

open access: yesYantu gongcheng xuebao, 2017
Based on different shear failure modes in rock uniaxial compression tests, the relationship among the uniaxial compressive strength, cohesion and internal friction angle is deduced by using the limit analysis method.

Size Effect of the Number of Parallel Joints on Uniaxial Compressive Strength and Characteristic Strength

open access: yes, 2022
The number of parallel joints has an impact on the size effect of the uniaxial compressive strength and characteristic strength of a rock; however, the relationships between them are yet to be derived. We studied the influence of the number of joints and
