The Advanced Cyclic Direct Simple Shear (ACDSS) system is designed to offer superior performance, accuracy and results for academic researchers and commercial testing laboratories. This state-of-the-art machine allows users to measure cyclic strength, liquefaction characteristics or cyclic properties of soils such as Modulus and Damping. Researchers can also upload stress ratio or strain time history files (e.g. earthquake motion) for analysis.
Cyclic direct simple shear testing requires the proper combination of frame stiffness and very precise load and volume control to produce reliable data. The ACDSS system is built to excel in these aspects. We've also incorporated technology and software features to ensure a broad range of user needs are met in terms of both ease of use and sophisticated options.
