Particle gradation and water content are important factors affecting shear strength of soil. However, due to chemical cementation and molecular attraction, loess particles commonly stick together ...

The non-coaxiality of the directions of principal stresses and principal plastic strain rates in granular soils under stress rotations has long been observed and recognized in soil tests using both ...

Lab is used primarily in undergraduate CET courses for concrete design and testing, aggregate testing, evaluation of soil properties and associated testing. Lab is also used by the concrete canoe ...

In engineering practice, the shear strength of finer grained materials (such as earthfill and tailings) are often characterized through field and laboratory testing. Yet for coarse-grained materials ...

The instructional geotechnical laboratory is used to conduct laboratory sessions that are part of the coursework for undergraduate classes. The lab consists of five triaxial cell setups which can be ...

President, Wyoming Test Fixtures Inc. In my October 2015 column, I compared three V-notched shear test configurations used to measure the shear stiffness and shear strength of composite materials: The ...
