Ph.D. and Postdoc on Mechanics and Biology

Submitted by Patrick Onck on

A Postdoc position is available at the University of Groningen, The Netherlands, to work on the mechanics of biological cilia. In addition, a Ph.D. position is available to work on the mechanics of the cell's cytoskeleton. Both candidates should have a university-degree in biology, physics, materials science or mechanical engineering, with a strong affinity for theoretical/numerical modelling. For a more detailled description, see the attachments below.

Productivity tools associated with the Internet

Submitted by Zhigang Suo on

One of the mission statements of iMechanica is to use the Internet to enhance communications among mechanicians. It seems that the top three uses of the Internet among many of us are

  • Emails
  • PDF
  • Google search 

It might be useful, and fun, for us to share the experience with these and other tools associated with the Internet.  I'll start a list of tools that I have found exceptionally useful.  All these tools are free of charge.

Hypoelastic-plasticity with logarithmic spin

Submitted by Biswajit Banerjee on

In small strain elastoplasticity we start off with an additive decomposition of the total strain into elastic and plastic parts. In terms of strain rates we write



Prior to 1990 most large deformation plasticity algorithms extended this idea by postulating an additive decomposition of the Eulerian stretching tensor (rate of deformation):


 

Derivative of Logarithmic Strain

Submitted by Biswajit Banerjee on

Some of you probably work on problems that involve moderately large strains. An useful strain measure for such problems in the logarithmic or Hencky strain. In particular, if you deal with the numerics of large strain simulations, you will often need to compute the material time derivatives of logarithmic strains.
