Overview of GDS' Large Automated Direct Shear System (GDSLADS). An electro-mechanical direct shear testing device for large samples, up to 300mm square or round. Different sample sets can be used to achieve the following types of testing in one system: Standard Direct Shear up to 300 x 300mm x 150mm, Geomembrane Shear test, Rock Mechanics sample set.

Luke Valvona, Pre-Sales Engineer at GDS Instruments talks through the features and benefits of GDS' Electro-Mechanical Dynamic Cyclic Simple Shear Apparatus (EMDCSS).

Mr. Efthymios Apostolou and Dr. Andrew J. Brennan from the Civil Engineering department of the University of Dundee, planned to carry to out some advanced physical modelling techniques in the Universities centrifuge. However, before using large amounts of soil in a centrifuge model and testing it under earthquake motions, it is necessary to test the material under shearing to check its behaviour, in particular liquefaction.
