TerraTek direct shear system
Hydraulic, stiff, closed-loop servo controlled, direct shear system. Load frame stiffness 7.0 MN/m (TerraTek DS - 4250). Normal force capacity: 1000 kN, Shear force capacity: 300kN. Shear box dimensions: 150mmX150mmX300mm. Normal load measured with a 1000kN LC with 0.5% linearity full scale. Shear load measured with a 300 kN LC with 0.5% linearity full scale. Vertical (normal) displacement measured with four 50mm range LVDT's with 0.25% linearity full scale. Shear displacement measured with two 50mm range LVDT's with 0.25% linearity full scale.
