How to compute the atomic stress objectively?
Earthquake in West China
After I put down the phone, my heart never felt so heavy. I just called my parents in my hometown, Chengdu, a city with 12 million people, which is just 90 kilometers away from the center of the strong earthquake at a magnitude of 7.9. It has killed more than 10,000 people so far. The death toll is still rising hour by hour.

Hi All, I'm presently working on modelling of guided ultrasonic wave scattering at defect using Abaqus/CAE. Can anyone help me with some tutorial materials on modelling of crack or notch in a through-hole of a plate? Warm Rgrds. Jo Ukpai |
Modeling DCB Specimen using Ansys to determine Energy Release Rate
Hi
Iam working on ansys modelling of DCB specimen to determine the energy release rate. Ihave modeled a CT specimen and determined its SIF. Is it right way to model the DCB by changing the dimensions of CT specimen and making it a DCB specimen?..
How can i find out energy release rate of the specimen?
Iam pretty new to Ansys
THANKS ALL

How to caculate stress? thanks
Hi,How to apply seismic accelaration on the BC in abaqus.thank you!:}
I am confused about apply BC of a model in abaqus. because I find that if I apply the accelaration of earthquake on BC, I must remove the fixed constraints applied on BC in previous step in abaqus. so the model become a free body without any constraints.
any expert can give me some detailed suggestions?thank you very much!^_^

Bloch-periodic boundary conditions in classical and enriched FEM
In the attached paper (accepted for publication), we present enriched FE formulations to impose Bloch-periodic boundary conditions. Bloch-periodic BCs arise in the description of wave-like phenomena in periodic media: periodic composites, Schrodinger equation in quantum mechanics, photonic band-gap materials, etc. For a perspective, see the J-Club on elastodynamic bandgaps and metamaterials that was organized by Biswajit Banerjee
