Journal Club for October 2016: Roughness evolution of biomaterial surfaces

As an example, here we discuss implant-associated infection from the mechanics point of view on bacteria adhesion affected by the biomaterial surface roughness:

1.    Implant-associated infection, a leading cause of failure in many biomedical devices, is caused by adhesion of bacteria to the surface of biomaterials. Implant-associated infection is difficult to treat, for example, joint replacement infections may occur deep around the artificial implants.

Dynamic creation and evolution of gradient-nano-grained structures in single-crystal metallic microcubes

In an article published today in Science, we have demonstrated the creation of an extreme gradient-nano-grained (GNG) structure in single-crystal microcubes through high-velocity impact. We use the defect-free single-crystal silver microcubes, synthesized using a seed-growth process, as the model system, and fire them at supersonic velocities onto a rigid target to create the GNG structure.

Assistant or untenured Associate Professor - Stanford University

The Department of Electrical Engineering at Stanford University ( invites applications for a tenure-track faculty appointment at the junior level (Assistant or untenured Associate Professor) in the broadly defined field of electrical and computer engineering. The department is especially interested in candidates in robotics and autonomous systems, hardware systems, and embedded systems. Priority, however, will be given to the overall originality and promise of the candidate’s work over any specific area of specialization.

Deterioration of the quality of the Elsevier journal printing

Many Mechanics journals are printed by Elsevier. Unfortunately, I observe huge deterioration of the quality of the printing.

Looking for a postdoc research position in the area of mechanical behavior of materials

My name is Zhan Zhixin and I got my PhD diploma of solid mechanics at Beihang University at January 16th, 2016. Now I'm looking for a postdoc research position in solid mechanics.

My Ph.D research program is about the experimental method for and theoretical research on the fatigue life calculation of defected structure based on damage mechanics, which focus on the fatigue failure analysis of metallic materials with impact or scratch defect considering residual stress, plastic damage and fatigue damage.

Abaqus Documentation



I installed Abaqus CAE and documentation. I am using documentation from the link that is provided in the final step of the installation. However, once I want to open the Help from the CAE, I get the following error:


The Abaqus HTML documentation collection could not be located. This may indicate that the HTML documentation was not installed, or a problem with the Abaqus installation.



How Can I fix this problem??

Quasi-periodicity and multi-scale resonators for the reduction of seismic vibrations in fluid-solid systems

This paper presents a mathematical model for an industry-inspired problem of vibration isolation applied to elastic fluid-filled containers. A fundamental problem of suppression of vibrations within a finite-width frequency interval for a multi-scale fluid-solid system has been solved. We have developed a systematic approach employing full fluid-solid interaction and dispersion analysis, which can be applied to finite and periodic multi-scale systems.

How to consider shear deformation effect in thin-walled FRP I-section beams in ABAQUS, for beams having low Length-to-depth ratios, i.e., L/d=3 ?

I modeled the beam with solid element and shell elements, in both cases load-deflection response is same. When I modeled the beam the shell element, I have prevented the shear locking effect by using reduced integration technique, i.e., by taking S4R element. The deflection of beam obtained from ABAQUS is lesser than actual deflection of beam.

Flaw sensitivity of highly stretchable materials

Elastomers and gels can often deform multiple times their original length. The stretchability is insensitive to small cuts in the samples, but reduces markedly when the cuts are large. This work shows that this transition occurs when the depth of cut exceeds a material-specific length, defined by the ratio of the fracture energy measured in the large-cut limit and the work to rupture measured in the small-cut limit.  This conclusion generalizes a result in the fracture mechanics of hard materials.
