Hardness Evaluation of Biological Tissue Using Nanoindentation

The ability to accurately measure mechanical properties, using Nanoindentation, in the fields of Life Science has recently become an important aspect of many current studies. In some cases, understanding the mechanical properties of soft biological surfaces have helped uncover the mechanical effects of diseases. Understanding mechanical properties provides a context for identifying the local mechanical behavior linked to specific changes.

Royalty Free Illustrations

Does anyone know of a good source for free science and engineering illustrations? I'm particularly interested in crystallography, crystal defects/dislocations, and mechanical properties illustrations.

Thanks

Measuring mechanical properties of nanoparticle in nanocomposite using nanoindenter

Hi There,

I am going to measure the mechanical properties of nanoparticle in Nano composite using nanoindenter. I searched through the literature and I did not find any work that measure this individually and all of them measured properties of nanocomposite not the inclusion itself. ThanksAzadeh

 

Finite Element Modeling On Polymer Nanocomposite with Clay Nanofiller

I'm doing Mtech project on Finite Element Modeling On Polymer Nanocomposite with Clay Nanofiller.  For that am using ABAQUS software,  so i need some information regarding that ABAQUS software, how to do finite element modeling of nanocomposites with nanofiller and How to prepare a code distrubution in the plate like particales in the polymer matrix with ABAQUS software. So please can any give information.

Mechanical properties of unidirectional nanocomposites with non-uniformly/randomly staggered platelet distribution

Unidirectional nanocomposite structures with parallel staggered platelet reinforcements are widely observed in natural biological materials. Our recent paper, published in J. Mech. Phys. Solids, is aimed at an investigation of the stiffness, strength, failure strain and energy storage capacity of a unidirectional nanocomposite with non-uniformly or randomly staggered platelet distribution.

Stiffening of organosilicate glasses by organic cross-linking

Atomistic simulations show that organosilicates, used as low-permittivity dielectric materials in advanced integrated circuits, can be made substantially stiffer than amorphous silica, while maintaining a lower mass density. The enhanced stiffness is achieved by incorporating organic cross-links to replace bridging oxygen atoms in the silica network. To elucidate the mechanism responsible for the enhanced stiffness, the conformational changes in the network upon hydrostatic and shear loading are examined.

Post-Doctoral Opportunities on Molecular Modeling, Strachan Group, MSE, Purdue University

We are seeking to hire an outstanding candidate as a post-doctoral fellow to work on large-scale molecular dynamics of polymers and polymer composites. The project focuses on the characterization of the molecular mechanisms that govern the mechanical responseof these materials. The successful candidate will work in the Strachan group and will have the opportunity to interact with experimentalists and theoreticians in academia, industry and national labs.

Tensile strength and fracture toughness of nanocomposite materials

Are not as high as we expected although very stiff and strong nanotubes or nanofibers (Young’s modulus E~1000GPa) are added into soft polymer matrices like epoxy (E~4GPa).  In our early investigation on the  systematic mechanical property characterizations of nanocomposites (Xu et al., Journal of Composite Materials, 2004--among top 5 in 2005;and top 10 in 2006 of the Most-Frequently-Read Articles in Journal of Composite Materials.) have shown that there was a very small increase (sometimes even decrease) of critical ultimate tensile/bending strengths, and mode-I fracture toughnesses in spite of complete chemical treatments of the interfacial bonding area, and uniform dispersions of nanofibers (click to view a TEM image). Similar experimental results were often reported in recent years. Therefore, mechanics analysis is extremely valuable before we make these “expensive” nanocomposite materials. Our goal is to provide in-depth mechanics insight, and future directions for nanocomposite development. Till now, nanocomposite materials are promising as multi-functional materials, rather than structural materials. Here we mainly focus on two critical parameters for structural materials: tensile strength and fracture toughness. We notice that other mechanical parameters such as compressive strengths and Young’s moduli of nanocomposite materials have slight increase over their matrices.
