conference

We would like to draw your attention to the advanced course at the International Centre for Mechanical Sciences (CISM) to be held in Udine (Italy) from September 8 through 12, 2014 on the topic of: "FERROIC FUNCTIONAL MATERIALS: EXPERIMENT, MODELING AND SIMULATION". The advanced course will comprise of distinguished lectures from the following experts:



- Kaushik Bhattacharya (Caltech, USA)

- Manfred Fiebig (ETH Zurich, Switzerland)

- John Huber (University of Oxford, UK)

- Doru C. Lupascu (University of Duisburg-Essen, Germany)

Job gets aborted due to cpset and nset history output definition?

Submitted by Manram on

Dear all,

 I am modelling an interactin between deformable and analytical bodies by utilisign Abaqus/Explicit. In order to define the contact between those objects I have selected surface-to-surface technique type and applied kinematic contact method as formulation method. As well I have selected individual output for a specially created set of my primary interest. Nevertheless, when I submit a job for analysis it gets aborted and the following warning errors appear:

The cpset or the surface parameter must be specified for history contact output

When is strong and when is weak by using extended finite element method?

extended finite element method
strong or weak discontinuity

As we know, the extended finite element method has been well used to simulate the localization band propagation and crack propagation without remeshing. It can deal with both strong discontinuity problems (displacement discontinuity) and weak discontinuity problems (strain or acceleration discontinuity). Now, I have always a question: when is strong and when is weak discontinuity using XFEM? In other words, what is the difference for the interpolation function and level set function or other function between strong and weak discontinuity? Thanks.

fracture of graphene
armchair
zigzag

In armchair graphene sheets, crack propagates perpendicular to the applied strain, whereas crack propagation in zigzag sheets occurs at an angle to the straining direction. This occurs due to different bond structure along armchair and zigzag directions as shown in Fig. 1. Videos 1 and 2 show the fracture of armchair and zigzag sheets, respectively.

MWR for the first- and third-order differential equations

Submitted by Ajit R. Jadhav on

Weighted Residual
Variational Methods

Hi all,

In engineering sciences, we usually end up using either the second- or the fourth-order differential equations, and the MWR (the method of weighted residuals) works pretty well for them.

The question is: how about the first- and the third-order differential equations? Why don't we see any applications of MWR for these odd-ordered differential equations? What gives?
