My ABAQUS notes

Submitted by machaka on

ABAQUS is a suite of powerful general purpose engineering simulation programs based on the finite element method.

1.1 Features

Abaqus contains an extensive library of elements that can model virtually any geometry. 

You may import geometry from a many different CAD software packages. 

The story behind the proof of Fermat's Last Theorem

Submitted by Joseph X. Zhou on

When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

Multiaxial behavior of nanoporous single crystal copper: a molecular dynamics study

Submitted by Kejie Zhao on

The stress-strain behavior and incipient yield surface of nanoporous single crystal copper are studied by the molecular dynamics (MD) method. The problem is modeled by a periodic unit cell subject to multi-axial loading. The loading induced defect evolution is explored. The incipient yield surfaces are found to be tension-compression asymmetric. For given void volume fraction, apparent size effects in the yield surface are predicted: the smaller behaves stronger.
