Multi-scale Modeling of Dynamic Behavior of Materials
If your research activites are related to modeling the dynamic behaviour of materials then you may consider participating in minisymposium 4.10 at
12th U.S. National Congress on Computational Mechanics
Raleigh, NC (July 22-25, 2013)
See attachment for details. The deadline for submitting an abstract is February 28, 2013.
Determination of Johnson_Cook model parameters
Hi All
Hope all are doing well. Suppose I have a specimen and I want to find out the Johnson-Cook material model parameters (A, B, C, m, n). Can any one tell me how can I proceed? Experimental or Numerical simulation??
Thanks in advance
Invitation to SES/ASME-AMD 2013 Symposium: Mechanics and Dynamics of Periodic Structures
We would like to invite you to a symposium entitled "Mechanics and Dynamics of Periodic Structures" as part of Society of Engineering Science (SES) 50th Annual Technical Meeting & ASME-AMD (Applied Mechanics Division) Annual Summer Meeting, Brown University, July 28-31, 2013. This special session aims to aggregate the latest research efforts contributing to the theoretical, experimental, and/or computational research on the mechanics and dynamics of periodic structures.
Load-displacement curve in static step using Abaqus.
Hi all,
I am working on Abaqus 6.8. I am doing a pile loading
analysis in dense sand. I am not understanding how to plot
load-displacement plot by using static general step. I mean where i
should assign reaction forces and displacement in output request. i have
assigned a set at middle of pile and requested for disp. in output
request also i have made a set of bottom which is fixed and ask for
reation force in output request. i summed up all reaction forces and
combine with displacement. but i am getting zero force and graph becomes
Need help for running UMAT of Dr. Huang's single crystal
Hello Everyone,
I am a new member of imechanica. I have started to learn UMAT of Abaqus to model my material behavior ( Cu6Sn5, HCP) using crystal plasticity finite element model. I found Dr. Huang's single crystal UMAT to start learning UMAT and I thought that it would be a great guide to start though it is written for FCC mat. But unfortunately I was not able to run the UMAT with it's input file.
link 8, introduced tensile curve and compression curve
Hi.
I'm working with the element link8 (Ansys 12.1) and I have to
introduced the tensile curve and compression curve, but I don't know,
How I have to introduced its???
I have worked with the comands: TB: aniso, miso,..., I think the best
option is: TB, user, but How I have to introduced the values of tensile
and compression curve?, when this are different.
File attachment is the tensile and compression curve to introduce
Thank you, Toni
