DETERMINING CHARACTERISTIC SAND SHEAR PARAMETERS OF STRENGTH VIA A DIRECT SHEAR TEST

Particle Size Effect on Shear Strength of Granular Materials in Direct Shear Test

The effect of particle size on shear strength of granular materials are investigated using direct shear tests. Small direct shear test (60 mm by 60 mm by 24 mm deep) were conducted for particles passing the sieves with opening size of 2.36 mm. Meanwhile, particles passing the standard 20 mm sieves were tested using large direct shear test (300 mm by 300 mm by 200 mm deep). The large direct shea...

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

A Test Method for the Determination of Shear Modulus and Shear Strength

Thi« report presents a method for determining shear modulus and shear strength of unidirectional flber-relnforced composites. The method Incorporates data from unlaxlal tensile and/or oompresslve tests at fiber orientations of 0, 45, and 90 degrees. The approach presented requires fewer specimens for shear strength determinations than current exlstinc procedures. ^ Distribution of this abstract...

Numerical evaluation of test setups for determining the shear strength of masonry

The bond shear strength between masonry units and mortar is the weakest link in a masonry wall. Different material tests have been developed in order to characterize this bond behaviour. The objective of this study is to evaluate three common test setups through non-linear finite element analysis. The simulation method is based on our recent development of cohesive elements, which allows for th...

Effects of Particle Shape and Microstructure on Strength and Dilatancy During a Numerical Direct Shear Test

ABSTRACT: Discrete element method offers insights into the soil behaviour at the microscopic level. In this investigation, a series of numerical direct shear tests is carried out by a three-dimensional discrete element code PFC. The size of the shear box is 6 cm long, 3 cm wide and 4 cm high. Non-spherical shaped particles are created by joining primary constitutive spherical balls together wit...
