Postdoc Position on Elastic/Acoustic Metamaterials at University of Missouri

Submitted by Guoliang Huang on Sun, 01/21/2018 - 04:17

Composite Materials & Dynamics Laboratory (http://cmdl.missouri.edu/) at University of Missouri develops innovative solutions for Solid Mechanics and Structured Materials, in particular the new frontiers of structural dynamics, wave propagation, micromechanics, topological and quantum mechanics, smart materials and dynamical behaviours of multi-functional materials, both man-made and formed naturally, and understanding relationship between microstructures and material macroscopic properties.

concrete steel stress strain compression tensile

The concrete stress-strain curve corresponds to the compression case with negative values plotted on positive axis. If one needs to plot the tensile curve for this concrete material this will be almost similar with {0.1*compression} stresses with positive values. Furthermore if one needs to plot on the same axis the tensile steel and concrete stresses for a composite mixture he needs to consider this last case. Fortunately the tensile and compression steel stresses are quite similar with opposite values.

Experimental Study of Natural Convection from an Array of Square Fins

Submitted by keyhani on Sat, 01/20/2018 - 04:05

research

In this research, we experimentally investigate natural convection heat transfer of three finned-tube exchangers with an array of square fins and a fin spacing of 5, 9, and 14 mm. The exchangers are in a 5.8m x 4m x 3m control room where temperature and humidity are automatically controlled with heating, cooling, humidifying, and dehumidifying equipment. We changed the surface temperature of the center tube by varying the input power of the heating element from 8.4 to 56.7 Watts.

Understanding Homogeneous Nucleation in Solidification of Aluminum by Molecular Dynamics Simulations (OPEN ACCESS)

Submitted by mohsenzaeem on Fri, 01/19/2018 - 15:07

Homogeneous nucleation from aluminum (Al) melt was investigated by million-atom molecular dynamics (MD) simulations utilizing the second nearest neighbor modified embedded atom method (MEAM) potentials. The natural spontaneous homogenous nucleation from the Al melt was produced without any influence of pressure, free surface effects and impurities. Initially isothermal crystal nucleation from undercooled melt was studied at different constant temperatures, and later superheated Al melt was quenched with different cooling rates.

Flexoelectricity in Bones: A nanophenomenon that triggers the bone-repair process

Submitted by Amir Abdollahi on Fri, 01/19/2018 - 09:23

Bones generate electricity under pressure, and this electromechanical behavior is thought to be essential for bone's self-repair and remodeling properties. The origin of this response is attributed to the piezoelectricity of collagen, which is the main structural protein of bones. In theory, however, any material can also generate voltages in response to strain gradients, thanks to the property known as flexoelectricity.

Introduction to Simpleware Software Workshop, London, Feb 8th

Submitted by Simpleware on Thu, 01/18/2018 - 10:54

This workshop is aimed at those interested in obtaining high fidelity models from 3D image data. You will experience first-hand how quick and easy it is to visualize and process 3D image data (CT, MRI, FIB-SEM...), and generate models for CAD design, FE/CFD simulation and 3D printing. If you are working in areas such as Materials Science, Industrial Reverse Engineering and Life Sciences, then this workshop is for you.

Free-to-attend but places limited, so learn more and register now.
