Finite Element Approach for Interaction of Highly Nonlinear Acoustic Waves with Linear Elastic Media
0.0 out of 5 stars
12 Jan 2011 | Poster | Contributor(s): Devvrath Khatri
In this work, we developed a threedimensional
finite element model (FEM) to study the
interaction of highly nonlinear acoustic wave with
adjacent linear elastic media. We compare...
Nanomechanical material size effects using an in-situ, on chip test platform
10 Jan 2011 | Poster | Contributor(s): Maarten P de Boer
Many micro- and nanoscale materials of interest (e.g., polycrystalline silicon, silicon carbide, carbon-based solids) are brittle.
Strength of brittle materials is not single valued, but is...
Stacked Rapid Sand Filters: An Economical Technology for Sustainable Development
06 Jan 2011 | Poster | Contributor(s): Michael James Adelman
Provision of safe drinking water represents one of the most significant global environmental and human health challenges. Filtration is an important component of water treatment systems, but it...
Understanding Fundamentals of Asphalt Concrete Materials using Discrete Element Models
04 Jan 2011 | Poster | Contributor(s): Yu Liu
Asphalt concrete is highly used for building highway or runway pavements, whose performances are not only governed by its components’ properties, but also impacted by loading and...
Piezoelectric Nanoribbon Assemblies Printed onto Rubber for Highly Efficient, Flexible Energy Harvesting
04 Jan 2011 | Poster | Contributor(s): Michael C. McAlpine
The research objective of this proposal is the hierarchical assembly of highly efficient nanoengineered piezoelectric materials onto rubber and plastic to harvest biomechanical energy for...
Data Integration and Model Development to Mitigate Urban Flooding Hazards Linked to Sea Level Rise
04 Jan 2011 | Poster | Contributor(s): Brett F Sanders
Urban geospatial data affords a high-resolution (ca. 1 m) representation of terrain heights, land cover, and civil infrastructure that, when coupled with flood simulation algorithms,...
NEESR-CR: Topographic Effects in Strong Ground Motion: From Physical and Numerical Modeling to Design
04 Jan 2011 | Poster | Contributor(s): Dominic Assimaki
Topographic effects refer to the modification and amplification of seismic ground motion in the vicinity of topographic features such as hillsides, ridges, and canyons. This well-documented...
Antibacterial Silica Nanoparticles Impact on Water Quality: Experiments Involving MF254A, Ralstonia pickettii species, in Ultrapure Water (UPW)
02 Jan 2011 | Poster | Contributor(s): Lisa Jones
According to the Center for Disease Control and Prevention, the public is being bombarded with ads for cleansers, soaps, toothbrushes, dishwashing detergents, and hand lotions, all containing...
Probabilistic study of cascading failures in complex interdependent lifeline systems
02 Jan 2011 | Poster | Contributor(s): Isaac David Hernandez-Fajardo
Urban distributed lifelines constitute the backbone of modern cities’ services. These systems depend on each other to serve large urban areas and growing population. Such conditions...
