Hi folks! I deal with buckling nanostructures, contact problem of nanostructures. And i have a problem with geometry construction of nanotube with arbitrary (n, m) chirality. Can any one write the algorithm for building nanotube geometry in 3d space(xyz-Cartesian coordinate system).  Many thanks!

Hi, everyone!

 Could you please tell me how can I use / calculate the element length when writting VUMAT for ABAQUS?

 Thank you!

Hello ABAQUS users!

 Do you know how to simulate the resonant frequency for a diaphragm with a liquid medium below as in the figure with ABAQUS ?

Zhigang Suo , Allen E. and Marilyn M. Puckett Professor of Mechanics and Materials at the Harvard School of Engineering and Applied Sciences (SEAS), founder and architect of iMechanica , has been honored with a Humboldt Research Award .

We invite applications for Ph.D. student positions in the Department of Mechanical Engineering, and Maryland NanoCenter, University of Maryland, College Park. We look for talented and motivated applicants interested in pursuing a Ph.D. degree in one of the following areas:



•    Mechanics of inorganic/organic hybrid nanostructures in flexible electronics

•    Mechanics of graphene-based nanostructures and nanomaterials



Requirements:

A post-doctoral research associate position is available immediately in the Department of Mechanical Engineering, and Maryland NanoCenter at the University of Maryland, College Park, in the area of multi-scale modeling (from atomistic, molecular, coarse-grained to continuum) of carbon-based nanostructured materials. Material properties of specific interest include mechanical and electrical properties, with special focus on deformation/failure mechanisms and bandgap engineering. 

Hello all,

I would like to seek help on a topic on which I am slightly ignorant.

I do not understand the concept of non local damage and the internal length of the non local continuum as described by the well quoted paper of Pijaudier-Cabot and Bazant (1987) in continuum damage mechanics.  So may I please ask the experts in this forum to please explain to me using some simple analogy.
