Why modulus of rigidity is not considered in shear test?
The modulus of rigidity, or shear modulus, is not typically considered in shear tests because these tests primarily focus on determining the material's shear strength and behavior under shear loading. Shear tests, such as the torsion test or direct shear test, measure how materials deform and fail under shear stresses, rather than quantifying their elastic properties. While the shear modulus can be derived from the initial linear portion of the stress-strain curve in some tests, the main objective is to evaluate the material's performance and failure characteristics under shear conditions.

What are true slump and shear slump in slump test?
A shear breaks off or crumbles. A slump stays together however it will slump down.

Differences between triaxial test and shear box test?
Shear box tests are generally suitable for cohensionless soil except fine sand and silt whereas triaxial test is suitable for all types of soils. Pressure changes and volume changes can be measured directly in triaxial test which is not possible in shear box test. Pore water pressure can be measured in the case of triaxial test which is not possible in direct shear test. Triaxial machine is more adaptable. The stress distribution across the soil sample in the failure plane is more uniform in triaxial test. The complete state of stress is known at all intermediate stages up to failure during the triaxial test whereas only the stress at failure are known in the direct shear test. In triaxial test, there is complete control over the drainage conditions, where control of drainage conditions is very difficult in shear box test.

How can one determine the shear modulus of a material?
The shear modulus of a material can be determined by conducting a shear test, where a force is applied parallel to the surface of the material to measure its resistance to deformation. The shear modulus is calculated by dividing the shear stress by the shear strain experienced by the material during the test.
Why vane shear test is done for clay only and not for sand?
Vane shear test is typically done for clay because clay is more likely to exhibit shearing behavior due to its cohesive nature, which requires a specific method to determine its strength properties. Sand, on the other hand, is generally considered non-cohesive and is better tested using other methods such as direct shear or triaxial tests to determine its strength properties.
Is hopkinsons test a direct test?
Yes the hopkinsons test is a direct test.
What are true slump and shear slump in slump test?
A shear breaks off or crumbles. A slump stays together however it will slump down.
Advantages and disadvantages of the shear box test?
Advantages: 1) The test's simplicity and, in the case of sands, the ease of specimen preparation. 2) The travel of the machine can be reversed to determine the residual shear strength values, which is shear strength parameters at large displacements. 3) Shear box represents a cheaper method in determining the drained shear strength parameters for coarse-grained soil. Preparing soil samples for other testing methods is relatively difficult and expensive. disadvantages: 1) The main one: drainage conditions cannot be controlled. 2) As pore water pressure cannot be measured, only the total normal stress can be determined, although this is equal to the effective normal stress if the pore water pressure is zero. 3) Only an approximation to the state of pure shear is produced in the specimen and shear stress on the failure plane is not uniform, failure occurring progressively from the edges towards the center of the specimen. 4) The area under the shear and vertical loads does not remain constant throughout the test.
