Ashby PhD Scholarship in the Mechanics of Materials
A fully funded PhD scholarship exists in the area of mechanics of materials, endowed in honour of Prof M F Ashby. The successful applicant will have a 1st class degree (and ideally a Masters degree) in an appropriate field. The precise topic of the PhD can be fixed after the scholarship has been awarded.
Further details may be obtained from Ms H A Gardner (has22 [at] cam.ac.uk (has22[at]cam[dot]ac[dot]uk)) .

A multiscale simulation framework of the ARB process
The accumulative roll bonding process is one of the most prominent severe plastic deformation processes for obtaining sheet materials with ultra-fine-grained microstructures and high strength. The properties of such sheets differ significantly from those of conventionally rolled sheets. It is hence desirable to have a simulation framework that can accurately predict the material properties, including the evolving texture and anisotropy during processing.
Now receiving submissions, Extreme Mechanics Letters – Special Issue on ‘Frontiers of mechanical metamaterials’
This themed issue on mechanical metamaterials invites contributions from different perspectives with the aim of highlighting the latest advances in the field.
The themed issue will focus on mechanical metamaterials in the general sense. This includes acoustic and elastic metamaterials as well as other types of metamaterials with unique mechanical and/or thermal properties at any length scale.
Topics of interest include the following:
Second derivatives of displacement field ABAQUS
Hello everyone,
I need to compute the second derivatives of displacement field in ABAQUS, in the integration point of quadratic elements if it is possible. I thought about using USDFLD subrutine, but I am stuck with getting the Jacobian matrix that couples the isoparametric space with the physical space in ABAQUS. GETVRM is what everyone suggests to get variables from abaqus, however I did not find the definitions of JMAC, JMATYP... so I do not know what I can get from that subrutine exactly.
Finger Motion Detection Glove Toward Human-Machine Interface
Finger motion capturing systems have a wide variety of applications such as telerobotics, rehabilitation, and avatar control. While commercial devices are too costly, studies on such systems are either impractical to use or have speed limitations. This paper proposes a practical version of the glovebased finger motion capturing system.
User friction model in Abaqus : how to code an hysteretic friction behaviour ?
Hello everyone,
I have to use an hysteretic friction model. I am trying to code this in Abaqus by using the FRIC subroutine. The language is Fortran 77.
I am testing my code on a very simple model : two plates sliding on eachother. I apply a 1 cycle sinus displacement at the end of one plate and a apply some boundaries at the other side.
