Recently, enlightened by the definition of inverse pole figure in Materials Science, I proposed an inverse-pole-figure (IPF) method for analysis of domain switching in polycrystalline ferroelectrics/ferroelastics.

Numerical implementation of a discrete damage model

Submitted by jretamav on Tue, 10/28/2008 - 17:58

Hi, I am implementing a discrete damage model with the discrete approach of embedded discontinuities but i have some problems. Could someone help me please?

I am using displecements and strains-displacements formulations of the finite element method.

Thank you for your help.

I am quite new to ABAQUS and trying to model structural masonry.I am facing difficulties in defining material property and analysis procedure.I was wondering if anybody has worked on this particular area and provide me with some useful resources.

Any Help in this regard will be highly appreciated

Thanks and Regards,

Modal analysis in ANSYS

ansys

Hi all,

I am doing modal analysis of a box placed at the table. The box is containing the electronics components inside. The electronic components are fragile to vibrations. Now i have designed the box in Pro E and have imported it in ANSY. The box is connected with the table at four corner points from the base. Note that the base of box is not placed at the table rather box is connected to table at four corner points.

Mechanics of buckled carbon nanotubes on elastomeric substrates

buckling

elastomeric substrate

We have studied the scaling of controlled nonlinear buckling processes in materials with dimensions in the molecular range (i.e., ～1 nm) through experimental and theoretical studies of buckling in individual single-wall carbon nanotubes on substrates of poly(dimethylsiloxane). The results show not only the ability to create and manipulate patterns of buckling at these molecular scales, but also, that analytical continuum mechanics theory can explain, quantitatively, all measurable aspects of this system.

efg method

efg 1d program

Dear Prof. Dolbow

In your 1D efg program, you have used u=d(1:nnodes). I think, you should calculate "u" by summing after multiplying with the shape functions and "d". Because in the figure 2 phi(x) is not equal to one at the node. Phi(x) satisfies the partition of unity.

Please clearify my doubt if I am wrong.

Best regards
