Abstract The paper focuses on the detailed analysis of dynamic characterisation polyurethane to evaluate effects injections into soil with aim geotechnical seismic isolation. To determine properties, resonant column (RC) tests were performed at University Kore Enna (Italy) specimens pure different values density and subjected mean confining pressures. results obtained by means RC tests, in term...

induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...

In the present work, we experimentally implement, numerically compute with, and theoretically analyze a configuration in the form of a single column woodpile periodic structure. Our main finding is that a Hertzian, locally resonant, woodpile lattice offers a test bed for the formation of genuinely traveling waves composed of a strongly localized solitary wave on top of a small amplitude oscilla...

Recycled concrete aggregate (RCA) is a relatively new construction material, whose applications can replace natural aggregates. To do so, extensive studies on its mechanical behavior and deformation characteristics are still necessary. RCA is currently used as a subbase material in the construction of roads, which are subject to high settlements due to traffic loading. The deformation character...

This paper addresses the differences between two approaches of damping estimation in resonant column testing: Steady-State Vibration (SSV) and Free Decay (FVD) method, at small (<0.005%) to medium (0.07%) strain range. The tests were conducted on “two types reconstituted sands” clayey soils” different relative densities confining pressures. test results suggested use SSV method measurement FVD ...
