This paper describes the factors affecting the test procedures and methods for preparation of test specimens for determination of tensile strength of soils by unconfined-penetration (UP) method. Correlation of tensile strength with other soil constants and strength parameters, such as Atterberg limits, activity, toughness index, unconfined compressive strength, cohesion, and friction angle, are presented. Theoretical explanations of this method and the conventional split-tension test by use of the limit analysis concept are discussed.read more

Factors Influencing Crack-Induced Tensile Strength of Compacted Soil
TL;DR: In this paper, the unconfined penetration device and experimental procedure were modified to reduce measurement errors, and it was then used to determine the tensile strength of compacted soil, including the plasticity index, rate of loading, and size of specimen.

Tensile strength of compacted and saturated soils using newly developed tensile strength measuring apparatus
TL;DR: In this paper, a tensile test was used for measuring the tensile strength of compacted and saturated soft soils with simple and quick testing procedure, and the average ratio of unconfined compression strength and initial suction test was found to be 12.5.

Novel Approach to Measuring Tensile Strength of Compacted Clayey Soil during Desiccation
TL;DR: In this paper, the tensile forces in a thin compacted soil layer are measured while simultaneously monitoring moisture content changes and crack formation via time-lapse photography, and results are presented from desiccation tests performed on two clayey compacted soils of medi...

Tensile strength characteristics of contaminated and compacted sand-bentonite mixtures
TL;DR: In this article, a theoretical and experimental study of the unconfined penetration test (UP) method was conducted to determine the tensile strength of contaminated and compacted sand-bentonite mixtures, which are used widely in the landfill construction sites as a clay liner.
