Mechanobiology post-doctoral position, Oxford, UK

Submitted by Mark S Thompson on

A postdoctoral research position is available immediately at the Mechanobiology Group, Nuffield Department of Orthopaedics, Rheumatologyand Musculoskeletal Sciences at the University of Oxford to study tendon mechanobiology and repair following injury or pathology. This is an exciting opportunity to join a multi-disciplinary team drawn from the Botnar Research Centre, the Oxford Institute of Biomedical Engineering and the John Radcliffe Hospital to work at the forefront of strategically important musculoskeletal research.

In situ observation of dislocation nucleation and escape in a submicrometre Al single crystal

Submitted by Daniel Kiener on

Dear colleagues,

Experimental nanomechanics is a frequently discussed topic on imechanica, see e.g. the very active monthly topics by Xiaodong Li, Julia Greer and Wei Cai.

Continuing on this, I would like to draw your attention to a paper we recently published:

"In situ observation of dislocation nucleation and escape in a submicrometre aluminium single crystal" by Sang Ho Oh, Marc Legros, Daniel Kiener & Gerhard Dehm (http://www.nature.com/nmat/journal/v8/n2/abs/nmat2370.html).

Importing Patran neutral file in to Ansys

Submitted by Zahra Zabolizadeh on

I imported the Patran neutral file (with *.out) in to Ansys(for a plate with a hole which was generated in the IDL and was imported in to the Patran) . but just the geometry of plate imported and i had not any elements, nodes (any mesh), and it reported in the Ansys. I also tried "import mesh " and nothing happend. could you please let me know what should I do?

How to choose what kind of element for particular problem (2D plane stress element or 3D solid element)?

Submitted by itbitb on

Dear all,

 

I would like to ask expert FEM users that how can we choose what kind of element for particular problem? Such as a plate (thickness t = 2.5 mm, W = 15 mm, L = 64 mm) subjected to axial tensile loading of cyclic loading, I should choose 2D plane stress element or 3D solid element?

 

It is really appreciated for all suggestions.

 

Kind regards,

Ansys - Concrete nonlinear beam

Submitted by Guillaume Gondre on

Hello,

I have to model with the Ansys software a beam in concrete material. It must be non linear.

In materials properties, I can choose Materials models - Structural - nonlinear - inelastic - non metal plasticity - concrete.

I put the Elastic Modulus, the Poisson´ratio, the uniaxial cracking stress and the uniaxial crushing stress. But I don´t know how I can enter the values of the strain at fc (compressive cylinder strength) and the value of the fracture energy.
