Get ready on Wednesday November 13, 2024 at 14:30, when the event starts online. Access to it is completely free, you must only register (and accept that your name and your home institution will be listed among participants).
We did it some 16 months ago - the 1st volume of this new online workshop was run without any budget and without any costs. Simply, a meeting place for researchers focused on a similar topic, and willing to share their experience with a broad auditorium. The content still can be found on our website, including records from all lectures.
Hi all,
I am trying to input a termperature field as initial conditions in
abaqus, to use the temperature distribution from a previous temperature
simulation in an mechanical simulation. But when I check the Temperature
values in the mechanical simulation i get great differences between the
nodal values (NT) and the element values (TEMP).
Does anybody know the reason of this problem?
Can it be related to the element typ? So the TEMP values are the avereged values from NT?

The velocities of atoms in MD simulation are not objective quantities, which depend on the choice of the reference frame and sample size. In our previous study (node/3181), we discussed how to overcome this non-objectivity and compute the atomic stress objectively. In this blog, our newly published paper on temperature computation is attached, and the abstract is as follows.
As we know, Abaqus/(v)umat provides the temperatures at each material point at the end of the increment, but in a thermo-mechanical problem, the heat induced by plastic deformation is unknown before the plastic strain is calculated. So, How the temperatures at material points in abaqus are updated?
Thanks in advance.

The dielectric constant is an essential electrical parameter to the
achievable voltage-induced deformation of the dielectric
elastomer. This paper primarily focuses on the temperature
dependence of the dielectric constant (within the range of 173 K
to 373 K) for the most widely used acrylic dielectric
elastomer (VHB 4910). First the dielectric constant was investigated
experimentally with the broadband dielectric spectrometer
(BDS). Results showed that the dielectric constant first increased
with temperature up to a peak value and then dropped to a
relative small value. Then by analyzing the fitted curves, the Cole–Cole
dispersion equation was found better to characterize the
rising process before the peak values than the Debye dispersion
Does anyone know where i can find the following?
-yield and ultimate tensile strength of cast iron and aluminium as a function of temperature
-fracture energy as a function of temperature for both metals
*the fracture energy i am referring to is for damage modelling in XFEM
Cheers
ABAQUS - DEGREE OF FREEDOM 11 AND AT LEAST ONE OF DEGREES OF FREEDOM 1 THRU 6 MUST BE ACTIVE IN THE MODEL FOR *COUPLED TEMP-DISP. CHECK THE PROCEDURE AND ELEMENT TYPES USED IN THIS MODEL.
Hi,
I’m trying to learn ABAQUS to simulate temperature-displacement problems.So, I’ve started on a simple example: two plates in contact, the 2nd presses and moves on the 1st plate (which is fixed).Could anyone tell me why the program gives me this error:
Hi all
I have a 2D model containing 2 2-D blocks rubbing on each other, producing heat at the interface. (Coupled temperature-displacement analysis in ABAQUS 6.8-1). This works fine, as the temperature on the contact surfaces in increasing.
Now, I want to get the instantaneous the heat flux per unit area due to frictional dissipation as a field output. Is there any standard subroutine or any other way to achieve that? There is no such a variable included in the standard ones.
Thanks!
Andreas
