Modern composite structures have a wide spread in their failure stress. Advanced multiphysics codes can have a wide range of predicted behavior for nominally the same inputs. How do we certify the design of such structures or the accuracy of such codes?

Very Much thanks to Mike for introducing Web 2.0 to me, I become more and more interested to Web 2.0, Imechanica in fact is part of this.

Hi All ,
I found simple VUMAT from Abaqus manual.It is based on
Von Mises plasticity and gives stress components, vonmises stress
and plastic equivalent strain.
I want to include the adaibatic temperature that rises/falls along the deformation in adiabatic
analysis.From a general book, i found that temperature-rise during deformation comprising
plastic strain1 to plastic strain 2 is given by:
Integral of stress between the strain limits,multiplied by a constant.
Science's Editor in Chief and "Friends" Discuss Peer Review and Journal
Impact. (July 4, 2008)
Bruce
Alberts1, Brooks Hanson2
and Katrina L. Kelner3 collaborated to write this
week's Science editorial on peer review. And if for no other reason
than the weekly has one of the highest impact ratings, when Science
speaks science administrators listen.
