As part of the advance laboratory testing program for Fundao Mine Tailings Dam Failure, KCB’s Vancouver Geotechnical Laboratory used GDS Instruments' EMDSS device to perform direct simple shear tests in order to obtain undrained peak and large strain shear strengths on monotonic simple direct shear tests; undrained response to cyclic loading on cyclic simple shear tests; and undrained response to cyclic loading on cyclic simple shear test with static bias.

Trilab Pty Ltd has just taken delivery of a new Cyclic Direct Simple Shear machine. This will compliment their existing Critical State Triaxial testing equipment. The simple shear is currently being used on a major tailings testing project.

Their state-of-the-art facility offers world class geotechnical testing of soil and rock for a variety of applications. Given that the current global pandemic has made visiting their new lab challenging, they have organised a virtual tour, follow the link in their article.

NGI increase DSS Testing Capacity with GDS' Electromechanical Dynamic Cyclic Simple Shear Device (EMDCSS).

Five EMDCSS's went through production last week. I guess working in a building by yourself does have some advantage.

GDS’ latest case study has been published in the renowned Ground Engineering magazine. The case study on the Fundão Mine tailings dam failure, has been prepared solely by GDS following its review and interpretation of the publicly available technical report.
