This example illustrates the use of the jointed material model in the context of geotechnical applications. The stability of the excavation of part of a jointed rock mass, leaving a sloped embankment was examined.
American Engineering Group (AEG) has developed a new “Dual Torsional Damper System”. This new AEG system design will allow varying static properties and provide dynamic shock and vibration mitigation over a wide load range for automotive and industrial applications. This dual structure system provides both axial and radial damping. The torsional damper system will have two elastomer elements with top element functions as a vibration damping element and the bottom spherical elastomer element as a noise & harness damping element. AEG dual mode damper system includes a spherical soft viscous bushing hub designed for being rigidly connected to a drive shaft, and an inertia ring, connected to the hub by means of a thin Polyurethane material layer. This dual-layer elastomer damper system is designed for torsional vibration reduction of the crankshaft system on multi-cylinder engine for vehicles. AEG polyurethane torsional dampers are designed to provide significant reduction of sou...
