Creep and shrinkage in concrete
Hey all. What is a good way to model creep and shrinkage in Abaqus for concrete material and what non linear material model will work the best? Any help will be greatly appreciated. Thank you.

23rd International Workshop on Computational Mechanics of Materials (Singapore, Oct 2 - 5, 2013)
Dear Colleagues, Co-Workers and Friends,
It gives me great pleasure to announce that the 23rd International Workshop on Computational Mechanics of Materials (IWCMM23) will take place in Singapore, Oct 2-5, 2013.
XFEM fatigue crack length
Hi all,
For my research I am using Abaqus 6.12 combined with XFEM crack propagation and direct cyclic analysis to asses the failure of bridge connections due to high cycle fatigue. Once propagation of an initially defined crack occurs I would like to plot the crack length at specific number of cycles. Is there an output request that can be specified that will measure that length of the crack as it moves through the simulation?
Thanks for any advice you can offer.

Principal compression and tension stress and strain plots
Hi,
I have a question with regards to the various stress-strain plots that I see from FEM softwares.
They have plotted principal compression and tension stress plots and strain plots for a 2d geomterical analysis from a FE software (MARC). They have used a finite strain theory. So does this mean that the principal compression and tension values for the various elements just correspond to the minimum and maximum values of a Cauchy green tensor or some other finite tensor like first or second piola kirchoff stress tensor??
Abaqus Simulation Run Time
Hey all,
I am running a wave propagation simulation on Abaqus that requires a large number of element and a very small time step(increment). I am using the Dynamic Implicit analysis type. When I run the simulation ,it take a very long time. I even tried using a faster computer(32 GB of RAM) but that did not reduce the time by much! Is there anything I can do to reduce the time it take that simulation to complete?
