Description

Soil Shear Strength Analysis with Automatic Direct Shear Testing

The Automatic Direct Shear Test is used to determine the shear strength characteristics of soil specimens under laboratory conditions. In particular, the test helps evaluate important strength parameters such as cohesion and the angle of internal friction. These parameters provide valuable data for foundation design, slope stability analysis and other geotechnical engineering applications.

The current ASTM D3080/D3080M-23e1 standard covers the determination of the consolidated drained shear strength of soils under direct shear conditions.

How Is a Direct Shear Test Performed?

Before testing, the prepared soil specimen is placed into a suitable shear box. A predetermined normal load is then applied to the specimen. After the consolidation stage, one section of the shear box is displaced horizontally at a controlled rate.

During the test, shear force and displacement values are continuously monitored. Tests performed under different normal loads allow the shear strength behaviour of the soil to be evaluated.

The resulting data can be used to determine engineering parameters such as cohesion (C) and the angle of internal friction (φ).

ISO 17892-10:2018 also specifies laboratory direct shear methods for determining the effective shear strength parameters of soils under consolidated drained conditions.

Automatic Testing and Data Evaluation

The test speed of the LT-S0260 Automatic Direct Shear Test Machine can be adjusted according to the test requirements. The official technical table specifies a speed range of 0.0001 to 9.9999 mm/min.

A large LCD display allows the operator to monitor test parameters easily. The machine can also be connected to a computer, enabling the test procedure and recorded data to be managed digitally.

The system supports automatic evaluation of test results. Relationships between shear stress and normal stress can be displayed graphically. In addition, cohesion (C) and internal friction angle (φ) can be calculated automatically, helping laboratories evaluate test results more efficiently.

When the programmed test procedure is completed, the machine can terminate the test automatically.

Suitable for Different Specimen Sizes

The standard configuration includes 60 × 60 mm shear box equipment together with a 50 kg slotted weight set.

Additional shear box assemblies are available for Ø60 mm, 100 × 100 mm, Ø100 mm and Ø2.5 inch specimens. Matching accessories include loading pads, retaining plates, porous plates, plane and perforated grids, specimen cutters and specimen extractors.

The LT-S0260 has a maximum shear force capacity of 5 kN. The normal loading system provides up to 5000 N vertical load when using the 10:1 beam loading arrangement.

The machine has external dimensions of 65 × 155 × 135 cm and weighs approximately 170 kg. Its electrical requirement is 220 V, 50–60 Hz, single phase.

Standards for Direct Shear Testing

The LT-S0260 product family supports direct shear testing according to ASTM D3080/D3080M, BS 1377-7, AASHTO T236 and ISO 17892-10.

The current ASTM edition is ASTM D3080/D3080M-23e1, while ISO 17892-10:2018 remains the active international standard. The previous ISO/TS 17892-10:2004 has been withdrawn and replaced by ISO 17892-10:2018.

Overall, the Automatic Direct Shear Test Machine provides controlled and repeatable determination of soil shear strength characteristics. Its adjustable test speed, computer connection, automatic calculations and multiple shear box options make it a comprehensive solution for soil mechanics and geotechnical laboratories.
