Dear Professor,

Could you also send me the documents? If there is an example for the head of the subroutine, it will be more helpful. Thank you in advance!

In reply to Equivalent Conwep pressure in abaqus

Description: Pressure loading due to an incident shock wave caused by an air explosion is calculated using the CONWEP model in Abaqus/Explicit. The new element field output variable IWCONWEP can now be requested on the element faces on which you apply this type of pressure load.

In reply to Sharing ABAQUS UMAT and VUMAT subroutines

Hello everyone!

I want to simulate the cracks formation in unsaturated soil using UMAT, does any one can help me to write the codes for that?

 

Thanks

In reply to Finite element analysis of a Euler Bernoulli Beam: calculations of natural frequencies with MATLAB

Hi Lagoue

why have you put the young's modulus in mN/mm^2 (206e+6) instead of N/mm^2 (206e+3), is this just a mistake?

In reply to Generate master curve for viscoelasticity

I can provide a recently written Matlab code (without extensive testing) for estimating a master curve from a discrete family of curves making use of fmincon. JG

In reply to You see a random microstructure.

43 years ago I took a special course (for 10-12 students) of Continuum Mechanics taught by Professor Barenblatt in Moscow State University. The course was structured more as a collection of problems united by his charisma and scientific interests, rather than a classical systematic course. Up to now I remember in details his facial expression, gestures, voice, and glance when he demonstrated an album of reproductions of van Gogh (it was a first album of van Gogh’s reproductions which I saw). Grigory Isaakovich explained the essence of material microstructure by the words “Look on these reproductions of van Gogh in my hands. And now look at the same pictures in your hands. You see a random microstructure.” It was a performance of the theater of one genius actor. I was shocked, impressed and encouraged. I did not could not estimate enough at that time who was Barenblatt, but I felt the God’s thoughts.

Only in a few years after graduation I began to work in micromechanics. From that time at each moment when I consider heterogeneous material a trigger is switched on in my mind “I see the random microstructure. It is myne.” The next paper is ready.

   The ideas of Grigory Barenblatt, his creativity, vision of similarity of different problems and their generalization, and his ability (that is most important) to generate absolutely unexpected points of view on any classical problem are with us forever.

What he offered was tantamount to removing the singularity at the crack-tip.

Thanks for showing us a way (and for loving mechanics, just the way we do), and R.I.P.

In reply to Re:How to bridge MD with DD

Dear Ill,

Thank you very much for your detailed explanations, which provide important insights to multiscale modelling. The hierarchical coupling you suggested might be effective for bridging between DD and MD, which would advance the understanding of plasticity from atomic level to dislocation level.
