Keynote speakers announced for the International Conference on Fatigue Damage of Structural Materials XI
The organizational committee for the eleventh biennial International Conference on Fatigue Damage of Structural Materials is pleased to announce that the following Keynote Speakers will be presenting at the conference.
Multi-scale Fatigue Modeling Keynote: David McDowell, Georgia Institute of Technology, USA
A nonlinear manifold-based reduced order model
A new perspective on model reduction for nonlinear multi-scale analysis of heterogeneous materials. In this work, we seek meaningful low-dimensional structures hidden in high-dimensional multi-scale data.
Contour plot
Hi,
I would like to do a contour plot for some output values in Abaqus and I was wondering if it would be easier to do it in Matlab or if there is a function in Abaqus where contour plots could be done.
How to obtain the Force-Indentation depth curve of nanoindentation FEA?
I did FEA of nanoindentation with using Abaqus and considered displacement of reference point (RP) on the indenter as a punching tool. Moreover, Abaqus/Explicit method was applied for solving problems.
But I do not know how to plot Force-Indention depth curve via FEA with using Abaqus.
Any suggestions would be greatly appreciated.

Rates of bond breaking between myosin and actin at different nucleotide states are systematically extracted for the first time
Recently, unusually high detachment rates of a myosin from actin were reported with a force spectroscopy technique. Here, we show that these high rates may be due to the coupling between bond breaking and state transition. Based on a kinetic model for single myosin, rates of bond breaking between myosin and actin at different nucleotide states are systematically extracted for the first time. Our results clearly indicate that myosins may adopt much higher transition rates than bond breaking rates at different nucleotide states at relatively low forces.

Conversion to particles formulation (SPH) using user subroutine–based criterion
Hello to everybody,
I wrote a VUMAT subroutine for a linear elastic orthotropic material.
In it I defined a state variable controlling the element conversion. When the condition for the conversion is satisfied, the SDV variable is set to be zero.
The subroutine works fine until the conversion criterion is reached. When that happens I get the following error: Abaqus Error: The executable explicit_dp.exe aborted with system error code 1073741819.
Problem in understanding table in VUHARD
Hello all,
I am trying to write damage model using isotropic hardening given in Abaqus example. But in VUHARD section some table is given like "syield=table(1, nvalue)" and eqpl1=table(2,k1+1). I dont understand what does it mean and where to put these values? If anyone can explain, it will be a great help.
Thanks
