Ongoing system development and testing is an important aspect of the work carried out by GDS Instruments. While numerous development projects are currently underway in the GDS office, one small endeavour of interest to GDS users is the availability of a vacuum mould for preparation of granular test specimens in the GDS electro-mechanical dynamic cyclic simple shear apparatus (GDS EMDCSS).
This mould, consisting of two parts, has been designed to enable a vacuum to be applied to the test membrane before granular material is placed inside the mould, securing the membrane tightly against the Teflon-coated lateral confining rings. Click here for the full article.
