New textbook includes an explanation of the concepts involved in the detailed analysis of composites, a sound explanation of the mechanics needed to translate those concepts into a mathematical representation of the physical reality, and a detailed explanation of the solution of the resulting boundary value problems by using commercial Finite Element Analysis software such as Abaqus.
hello,
as title says, does anyone knows how to fix a limit to the time that an abaqus job takes to be calculated.
this is because i am running several jobs sequentially, and i want to set that for instance if some job takes too much time, just stop it and go to the next one.
thank you a lot.
Hello:
I have written a UMAT subroutine similar to the one shown in abaqus 6.11 subroutine manual 1.1.40 with a slight differences indicative of the material's rheological model.
my expanded isotropic model looks like:
sigma_x - sigmav_x/3 + vbar*sigma_dot_x + kappa*sigma_dot_x =
lambda*eplv + 2*mu*epl_x + lamdabar*eplv_dot_x +2*mubar*epl_x
where:
sigma = stress
epl = strain
_dot_ are my rate change with time
sigmav = sigmaxx + sigma_yy + sigma_zz ( hydrostatic stress)
Hello,
I have an Abaqus 6.12-3 installed on a Windows 8 64-bit system.
Everything works smoothly. I am easily able to take control of the CAE
and model, define loads, steps, sections and jobs. The problem is while
running the jobs. The job aborts splashing an error "Unable to change
the current working directory to
C:\Users\ANIABU~1\AppData\Local\Temp\Ani Abu_I-beam_3876." This happens
with all the jobs. Rarely does the job complete successfully, but I am
unable to understand the underlying procedure. I did not request any
Hi,
i try to simulate a 3 points bending of a glass plate with abaqus.
force 1kN !
young modulus = 7e10 Pa
Poisson's ratio = 0.22
- the plate is square (30 cm) , thickness 8.72 mm
- i use 3D extruded solid
- for the load i can't create a line load so i replace this load by pressure in a thin surface (2mm*30cm) applied in the center of the plate
- C3D8R element type
but the results are strange:
Hi, I'm a Mechanical Engineering student and I need to learn how to create a simulation of the martensitic transformation as a result of quenching of steel using Abaqus.
I'm just trying to get as much information as I can on my own but I want to ask for some advise; at this time what I have found is that I may need to use some Abaqus user subroutines as UMAT or VUMAT ir order to succed on the simulation but I want to know if theres any other way to avoid using them.
Hello,
I have a question to Abaqus users,
Can I simulate a drop-test of a model having crack in it in Abaqus/explicit.
If yes, whether Contour integral crack type can be used or I have to use XFEM?
Reply asap

Hello!
I am trying to generate acoustic waves in aluminum bars and plates to simulate an experiment we are performing in the lab. We use piezoelectric actuators to generate and receive the waves in the lab. I know that similar simulations have been done in Abaqus, however, I an having difficulties getting the simulation to work. Is there a tutorial or does anyone have any experience with this kind of simulation? Your help is appreciated ! Thank you.
Cheers.
Dear All
I want to assign wind load on a 3D transmission tower USING abaqus, how can I assign the wind load on the transmission tower ? should it be assigned as a bodyforce or joint load ? your comments are highly appreciable.
Thank you
