Michael Carroll (1936-2016)

Submitted by oliver oreilly on

Many in this community may have heard the sad news of the passing last weekend of Michael Carroll.  Two obituaries have been posted: one at U.C. Berkeley where he was a faculty member for many years and another at Rice University where he was a former Dean of the College of Engineering.

How VUMAT works for elements with more than one integration point?

Submitted by J_Fan on

Hi everyone

I am working on vumat subroutine for abaqus explicit. I know in the umat, the subroutine is called for each integration points. There are an argument that stand for integration number. So, I can output information (such as deformation gradient, stress ...) for each integration point.

However, in vumat, there's no arguments for integration points. I can only output element numbers. My question is, for an element with four integration points, how can I output information for each integration point? How the vumat is called for each integration point? Thank you!

polyrethane

Submitted by DRIDIAFEF on

Hello everybody

well i am new in modeling of polymers in abaqus. I would like to test the uniaxial test in traction of polyrethane. I did the experimental test i took the data (strain and stress) and used it in modeling in abaqus the numerical test. i chosed the hyperelastic response. My question is : 

is my choice good (hyperelastic behaviior) 

when i run the job i have no permanent deformation but when i unload the specimen return to its initial position.

Any suggestion or help please

Submitted by Shaoxing Qu on

Zhejiang University (ZJU) is one of the earliest and most prestigious universities in China. Department of Engineering Mechanics, taking comprehensive advantages of ZJU and School of Aeronautics and Astronautics, focuses on multidisciplinary research in Solid Mechanics, Fluid Mechanics, and Dynamics and Control. ZJU is seeking faculty candidates for its newly launched, highly competitive and well-funded “Hundred Talents Program” according to the tenure-track rules.

Reading unfortunate Planck

Submitted by Zhigang Suo on

Planck submitted his doctoral dissertation in 1879, at the age of 21. According to Planck’s autobiography, his dissertation elaborated on Clausius's entropy and its role in distinguishing reversible and irreversible processes. His dissertation failed to interest his professors, Helmholtz and Kirchhoff among them. Planck subsequently, as a young academic, applied the principle of the increase of entropy to analyze phases and ideal-gas mixtures.
