Biographical Memoir of Zay Jeffries by W.D. Nix

Submitted by William D. Nix on

I have written a National Academy of Sciences biographical memoir of Zay Jeffries, one of the great American metallurgists of the 20th century.  I am posting the link to the NAS website here with the thought that some readers of iMechanica might be interested in the piece.  Some will be interested to learn that Jeffries came very close to discovering dislocations some 18 years before the great papers of Taylor, Orowan and Polyanyi in 1934.

Having learned Python for a while now, I believe it is of benefit to students who want to learn statistical analysis and such models and be able to compute these. Python is an easy to learn language. Oh and did I mention George   his is for  you ;)

Abaqus verification

Submitted by dooman_ak on

Hello everyone

I have a question about Abaqus verification for a Mooney-Rivlin
hyperelastic material example which exist in ABAQUS Documentation/Abaqus
Verification Manual/2.2.1 Elastic materials/VIII. Hyperelasticity with
Mooney-Rivlin strain energy function. In the example for a Test data
input-uni axial tension the company Defined a stress-strain curve as
input for material property(Nominal stress-Nominal strain). But when I
plot these parameters(Stress -nominal strain) as output of the software
