Prony series for viscoelasticity in Abaqus.

Submitted by priyadd84 on

Hi all,

     My first question is i have a set of stress Vs strain data for different strain rates (100/s to 350/s). Can prony series be extracted using these data? Or is there a way in Abaqus i can enter directly this data?

    After reading for a while a came to know that stress relaxation data is needed for defining pony series. My second question is can stress relaxation data can be obtained for high strain rates in the order of 100 to 350/s?

Thanks all

Dear all,

 

I have two two model each is containing one part. I want to bring those two parts  from the two model into one entirely new model. It would be highly appreciable if  anyone of you kindly give a solution of this issue.,

A question on Residual Load Vector in Abaqus User Element Subroutine implementation

Submitted by Gurudutt Chand… on

Hello all,

 

I am implementing a Finite Shell element in Abaqus as a User Element.  I have a question regarding the Residual Lod vector that has to be defined in the User Element Subroutine.  

We know that K(du)=R-f       where R is the external force vector at time t+dt

Magnetic bodies undergoing large deformations: how should we pull magnetic fields back to the reference configuration?

As is well known, the formulation of the equations describing a deformable solid is best done in the Lagrangian setting. For magnetized solids, however, one needs to take into account the magnetic field $h$ and the induction field $b$ generated by the body, whose description is usually done in the Eulerian setting.

Coupled Euler-Lagrangian FEA to simulate fluid entering micro pores in Abaqus/Explicit

Hi all,

         How to model a pipe which has pores in its internal surface, when the pipe is filled with water and closed at the both ends. Now when the pipe is impacted in the 3 point bending mode water will enter in side the pores and will cause some damping (resist bending).
