The special issue on "Computational and Theoretical Materiomics: Properties of Biological and de novo Bioinspired Materials" has now been published. A list of papers is included below. A sincere thank you to all contributors! Anyone interested in a reprint of any of the articles please send me a message.
What is stress? Who has ever seen stress? Is stress a physical quantity?(second section) Let us re-consider an example for metal foam as show n Figures 1(a,b) that show the local flexuosity under cycle compression loading. Previous researchers used the effective elastic moduli theory and the effective stress concept to study this kind of problem. However, who know what are the approximate stresses at any point in the form, say, at the points A, B, A’, B’?

For a steady shock wave, since we know Rankine–Hugoniot relations,and Equation of state,
from downstream values, we can directly calculate upstream values, we know all the quantities, density, particle velocity, specific energy are functions of z (where z=x-ct), but, how to relate these quantities to z, and how to plot a S-Shape curve like density vs. z.
Dear colleagues,
Apologies for cross postings.
The second ECCOMAS Thematic Conference on the eXtended Finite Element
Method (XFEM) will take place in Cardiff (Cardiff University) in the
period 29 June - 1 July 2011. [see http://www.xfem2011.com for
details]
We would like to invite you and your students to submit original
research contributions in the area of partition of unity enrichment.
The present study is motivated by two classes of seemingly contradicting experiments on the effect of humidity or the capillary effect on adhesion. While one class of experiments suggests strong effect of humidity in gecko adhesion, those on micromachined surfaces indicate that the adhesion energy remains constant up to a relative humidity of 60–70% even for hydrophilic surfaces. To resolve this apparent paradox, we perform numerical simulations of the vertical peeling of a spatula pad adhered to a rough surface with periodic attachment sites.
Hello,
I want to do transient analysis of piezoelectric actuator with varying preload acting on it in ANSYS. I really dont know how to proceed with. Can anybody suggest me how to proceed with some apdl examples.
Thank you

Load-bearing biological materials such as shell, mineralized tendon and bone exhibit 2-7 levels of structural hierarchy based on constituent materials (biominerals and proteins) of relatively poor mechanical properties. A key question that remains unanswered is what determines the number of hierarchical levels in these materials. Here we develop a quasi-self-similar hierarchical model to show that,
