LoadTrac II/FlowTrac II

The LoadTrac-II/FlowTrac-II system for triaxial (CU, CD, and UU) and stress path testing fully automates triaxial stress path tests on soils and soft rocks. This system operates by software which automates the initialization, saturation, consolidation (isotropic, anisotropic, and Ko) and shear phase along any stress path (drained, undrained, or mixed) of a test. Consolidation and shear phases contain up to 32 steps. This system allows specifications of all steps required to perform a triaxial stress path test along any stress path test possible in a triaxial cell, including the ability to specify changes in pore pressure.
