This paper analyses the permanent deformation performance of an unbound granular material for base layers of low traffic roads. The material has been subjected to repeated triaxial loads. Three models were fitted to express the cumulative permanent strain as a function of the number of load cycles. In general, the predictions of two models previously studied by other researchers proved to be go...

We conduct a finite element analysis of the slice compression test [13] applied to metal-matrix composites. This test, designed to characterize interfaces in composite materials, involves pressing a composite material specimen on a soft plate so that fibers are forced to protrude and intrude into the soft plate leaving a permanent deformation. We focus on the Ti-6Al-4V matrix with SCS-6 silicon...

New GPS estimates of relative motion across the Jura Mountain Belt with respect to the Eurasian Plate indicate less than 1 mm/ yr of convergence, considerably less than previous estimates. Velocity uncertainties have been evaluated by several methods and range from 0.2 to 0.5 mm/yr for the semi-permanent stations. The major, statistically-significant strain feature inferred by the Jura GPS meas...

High cycle-life is important for shape memory materials exposed to numerous cycles, and here we report shape memory polyimide that maintained both high shape fixity (Rf) and shape recovery (Rr) during the more than 1000 bending cycles tested. Its critical stress is 2.78 MPa at 250 °C, and the shape recovery process can produce stored energy of 0.218 J g(-1) at the efficiency of 31.3%. Its high ...
