Hello everyone !
I'm new to abaqus and have a problem with the shell-solid assembly. I want to model a shell element (plate) clamped into two solid elements (parallelograms) on its top and bottom edges.
I've tested different possibilities to do my assembly (shell-solid coupling, merging the geometry or the mesh when assembling the two elements) but none of them work. There's always a problem whis the definition of the elements' properties when I submit the job.
Does anobody have a solution ?
I am studying the response of a bridge in MATLAB, and have successfully retrieved mass and stiffness matrices from Abaqus using the following keywords:
*Matrix generate, STIFFNESS, MASS
*Matrix output, STIFFNESS, MASS, FORMAT=COORDINATE
New Technologies Research centre at the University of West Bohemia
(Czech Republic) invites applications for a Postdoctoral position in the
field of Computacional Mechanics of Materials. Highly motivated
individuals holding a PhD in Mechanics, Materials Science or closely
related fields are encouraged to apply.
I am quite new in this area.
Somebody can give me an idea on:
How to impose aqua loads by phyton scripting in abaqus?
Thanks in advance
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.
It is showing error " Too many attempts were made for this increment". I have no idea where I went wrong as I just ran the UMAT with it's own physical model. Please can anyone provide me a running UMAT of Dr. Huang ? I think there is something I need to change. Also, guideline for learning UMAT will be a great help.
i work on a bio mechanic project. i am going to simulate a mandible bone
with implant. at first i want to use Materialise Mimics V10 to convert Ct Scan
data of a mandible without implant to a 3D model. i thought i could edit
the exported file on the other software (Ansys or Abaqus) to add the
implant. but, exported file from mimics can not have any edit .Actually
it has not volume and i need to have a 3D solid model. please help me !
This is my first post in imechanica and i hope you can help me, im working in my finall project to obtain my MsC, im working in the simulation of crack growth in freeting fatigue, i found usefull the article post in imechanica by Eugenio Giner http://www.imechanica.org/node/4338. Im having problems with the preprocessin files, Can you help me with some information about how to create the input files? (i have some basics using ABAQUS CAE, but i dont know how to create the input files like mOXY.prn, TopNox see article)
Thanks for your help and sorry for my bad english

can you help me to define a cyclic load of 1 kN (120 cycle per min ) in Abaqus?
does it diifrent to use static or dynamic analysis?
is there a way to get the characteristic length of one element? I wanna calculate xult (when the element is cracked, fracutred..).
I use the concrete damage plasticity model and after reaching the tensile strength i assume a linear softening with fracture energy.
max. tensile strength
when do i reach xult or what is the plastic strain equivalent
I'm recently very interested in computational nolinearity. Would you like recommend some monographs on the computation nonlinearity so that i can have a better understanding of the mechanism of ABAQUS.
I recently find an example in ABAQUS documentation cannont convergence.
The parametres related with the iteration of the Risk method is
does anybody know, what is this strange error : Error in connection to analysis
i am trying to model fracture mechanics on piezoelecteric material, when i select the piezoelectric as a familiy in mesh part, then when runing the model, i recieve this error. if anybody knows how to fix it please help me.thanks
Dear valuable members,
Thanks for the kind help in advance.
I would submit a well known error that I got in my run of
the UEL subroutine which has additional dof. the error is:
I am using the VCCT method to model crack propagation and I am finding the value of G/Gc is too large for any sensible time step (1e-25).
I am attempting to incorporate a time incrementation scheme into my UMAT which monitors EFENRRTR and modifies the time step (or PNEWDT) according to it's value.
Hi, I am new to ABAQUS. I want to simulate the fracture toughness test to predict the behaviour of materials(brittle/ductile). Please help me how can I proceed?
If possible give me some guidelines and if you have any documents regarding this topic kindly send it to: email@example.com
Thanks in advance for your valuable suggession.
We are pleased to announce the keynote presenters for the 2013 SIMULIA Community Conference! Hear firsthand how BMW Group and Ethicon Surgical Care, Inc., a Johnson & Johnson company, use SIMULIA solutions to stay ahead of the competition—keynote presentations by:

Please apply online. Do not contact me; I do not work in the company.
The Research and Computer Aided Engineering group at Carrollton Technology Center of Halliburton is looking for an expert FEA analyst at principal engineer level. This position requires
1) Extensive experience with nonlinear finite element analysis and fundamental understanding and knowledge of Solid Mechanics.
Ice or hail impact is an important design consideration in the aviation, energy, and astronautics industries. Physical testing of impact scenarios can be expensive and impractical. Numerical simulations provide cost effective and convenient tools for including hail impact scenarios in the design process.
Numerically simulating high speed ice or hail impact is challenging because of the extreme deformation, fragmentation, contact, and material model complexity.
I hape a relatively simple question. I am trying to set a maxmimum time step for a job by the lines:
*Static, allsdtol=0, continue=NO
0.05, 1., 1e-25, 0.05
so I believe the maximum time step should be 0.05 giving me a minimum of 20 increments in the step in total. However the STA file below shows that the job starts at 0.05 and the appears to ignore the maximum time step command. Can anyone tell me why this occurs?

SUMMARY OF JOB INFORMATION:
Does anybody how we can put a loop (for example while loop) inside a .psf (parametric study) file in abaqus?
For example a loop on all the increments we want to get a field variable output. Take a look at the following code:
I am doing an explicit analysis, i am trying to model a woven fabric structure. I have to pre-stress the fabric so i have used this option.
