Hi,
I'm a fresher in abaqus. Now I'm trying to simulate the damage of brittle kind of materials, like concrete with abaqus on mesoscale. But there are some problems now...
One of the most significant factors in molecular dynamic simulatin is to choose the proper potential. Recently, I did some searching jobs on Vanadium (V) potential and finally decided which potential I am going to use. Here is a simple summary:
A brief introduction of EAM, F-S and MEAM potentials for BCC transition metals
Hi,
I'm a fresher in abaqus. Now I'm trying to simulate the damage of brittle kind of materials, like concrete with abaqus on mesoscale. But there are some problems now...
The random meso-structure has already been generated by matlab, but I don't know how to import the information of the geometry which are some coordinates? I find the file formats which could be read by abaqus, like Autocad .dxf,.step...but I'm not sure how to do it exactly since geometry information are in terms of coodinates in matlab.
Hi all,
I am new in the Forum, and I am looking for some informations regarding how to simulate nonlinear material in explicit.
I am tryng to analyse the behaviour of a roller rolling on the sand (or mud), but the results I get with a basic elasto-plastic material are not very accurate, expecially because I cannot set the tension allowed in the sand to be zero.
Other ways to input nonlinearity in Explicit are always refused by ABAQUS. Is there any way to get something more accurate?
Dear all,
I have read the paper titled Haversian cortical bone model with many radial microcraks: An elastic analytic solution. My problems and the paper are attached.I hope you can see the problems and the corresponding paper. Thanks for your help.

I am currently involved in performing dynamic analysis of particular
assemblies and working in ansys workbench 12.0. Currently I am stuck with a
problem, while performing harmonic analysis I need to input displacement as a
tabular function of frequency but inspite of all my efforts could not find a
solution to this problem. Also the assembly is connected to the vibrating base
via mounting feets. Now in that case should the displacement field be applied
to the holes of the mounting feet or the entire base plate of the assembly that
Dear everyone,
Recently I have read the paper--Haversian cortical bone model with many radial microcraks: An elastic analytic solution. In this paper, I can't understand the dislocations Burgers vectors (bt and bn), the following words and the corresponding expressions(6a) and (6b). The paper is attached.
Now, if it is assumed that bt and bn are continually distributed
over the microcracks, the shear and normal stresses could be
formulated as (6a) and (6b).
Waiting for your help. Thanks.
i am doing structural analysis of composite barrel with load sharing steel liner from inside and IM7/PEEK composite sheathing outside. Can anyone guide me how to model composite sheathing material. i am using axisymmeteic model for analysis. loading is pressure from inner surface and temperature gradient across the thickness of cylinder.
thanks.
