Stabilizer cyclic testing

Determination of these soil properties are well established with recent advances in the formulation of nonlinear hysteretic constitutive relations for soils and the characterization of stiffness degradation of saturated sands and clays with cycles of loading. The increasing interest in seafloor slope stability problems imder wave and earthquake loadings has also emphasized the need for data from cyclic tests simulating stress conditions on slopes. The application of cyclic test techniques in relation to the latter developments are discussed with reference to both test results and associated analytical approaches. 

The cyclic stability (data are not shown) was also tested. After 2000 cycles, there is only a loss of 7 % in the acidic medium. This supports our view that N-doped carbons possess a significantly improved chemical stability. 

Like all the phosphates investigated as cosolvents, TBP and TPP showed higher anodic stability, as confirmed by their cycling in lithium ion cells based on a LiNio.8Coo.2O2 cathode up to 4.2 V, and separate cyclic voltammetry tests also showed that they would not decompose anodically below 5.0 V on an inert working electrode. Little capacity fading was detected during the extended tests of TPP or TBP in full lithium ion cells up to 150 cycles. 

Syntactic foams absorb considerable amounts of water only at hydrostatic pressures above 100 MPa (Fig. 14), but absorb very little between 20 and 100 MPa u. A good feature of syntactic materials is their stability in cyclic hydrostatic tests. They can withstand up to 1000 cycles of alternating 60 MPa and atmospheric pressure 16).
