Stability analysis of retaining structures carried out at unsaturated conditions mainly dismissed the effect hydraulic and mechanical hysteresis on exerted active thrust. This paper reports a parametric study into influence as well soil types earth pressure low high suction profiles to envision pattern thrust for various simulated soils, from sands clays. Generally, numerical results exhibited ...

The data management plan of the Community Earth System Model (CESM)[1] from the National Center for Atmospheric Research (NCAR) is given historical context and its policies, definitions, and features are detailed. The drivers of CESM data management are discussed, including the upcoming Coupled Model Intercomparison Project 5 (CMIP5), the ongoing Earth System Grid (ESG) project, and the strateg...

Earth-based materials are currently receiving high attention, as they considered sustainable. In addition, the reuse of waste and more particularly recycled aggregates can boost circular economy while reducing landfilling mineral resource depletion. Incorporating in earth concrete be an innovative way to valorize them. However, investigations required concerning their long-term behavior. Such a...

Despite the fact that shape-memory alloy (SMA) has several mechanical advantages as it continues being used as an actuator in engineering applications, using it still remains as a challenge since it shows both non-linear and hysteretic behavior. To improve the efficiency of SMA application, it is required to do research not only on modeling it, but also on control hysteresis behavior of these m...

In this paper, experimental and Finite Element Methods have been used to determine mechanical properties of nanocomposites. Standard tensile and compression samples with 0.0, 0.15, 0.25, 0.35, 0.45, and 0.55 weight fraction of Multi-Walled Carbon Nanotube (MWCNT) were prepared and tested. Nanotube weight fraction was varied to investigate the effects of nanotube weight fraction on nanocomposite...

The aim of this work is to study the possibility reuse tunnel excavated earth in order elaborate earth-based mortar for rammed reparation. mortars were compared with raw based-mortars, largely used practice. cement was as stabilizer and hemp fibers diminish cracking due shrinkage. mechanical, thermal hydric properties characterized after 28 days. maintained hydrothermal chamber at controlled co...

Distribution of Pand Swaves velocities in the Earth’s inner core suggests that its matter has been quantum entangled since origin Earth and Solar system. This assumption we made allows us to develop model geomagnetic field evolution from start disappearance. Unlike generally accepted dynamo our provides an obvious source energy which is a phase transition thermal, mechanical electrical released...
