Displacement control VS. force control in Abaqus
Dear friends,
I have modeled a simply supported beam, using wire and the circle section of 1mm and a length of 110mm. I did two analyses
1) I used the distributed load of 0.2 N/mm (where the beam behaves in
the elastic area) and got the maximum displacement (at center).
2) I used the obtained max displacement (from first analysis) as a
displacement control. the results of the reaction forces are supposed to
like the distributed load at first analysis, but it is much lower.
need help in ansys
sir,
I need to find out kinetic energy of the element in the harmonic analyis problem of a plate.
i am using ansys command...in /post1
etable,KE,KENE
but no data is stored on the lable KE
please help and suggest some other means to do the same...or the correct method of issuing this command ..
thanks

Tensile test under LS-DYNA
Dear all,
I would like to run a tensile test under ls-dyna of a mild steel and
apply a 7000 N load to the dog bone specimen on a explicite scheme.
Unfortunately, I
have wild deformations ( and an error) on the nodes on edges where the
load is applied, so can you please tell me what are the importants
constants (like time termination, mass scale,...) and how to perform a
perfect run?
Have a good day,
Thank you
M.

MultiScale Simulation of CNT and nanocomposite
Hi all
I am a beginner on MultiScale Analysis.
I am studying on "MultiScale Analysis of Carbon Nanotubes and nanocomposites".
is there any commercial software or open source program for multiscale modelling of CNT and nanocomposites??
The surface effect on the strain energy release rate of buckling delamination in thin film–substrate systems
Gurtin–Murdoch continuum surface elasticity model is employed to study the buckling
delamination of ultra thin film–substrate system. The effects of surface deformation and
residual stress on the large deflection of ultra thin film are considered in analysis. A
concept of effective bending rigidity (EBR) for ultra thin plate is proposed on the basis of
Gurtin–Murdoch continuum theory and the principle of minimum potential energy. The
governing equations with EBR are formally consistent with the classical plate theory,
Hi all,
Hi all
Do i have to use geostatic step when i use hermal expansion to analyze single pile in expansive soil?
No Application will be considered--- Research position for doctoral candidate or postdoc at TU Darmstadt, Germany
No more applications will be considered for the above mentioned the position.
Thank you for the interest.
Wave propagation simulation in elastic bar
Hi ,
I'm working on simulation of wave propagation in a bar. I'm using
newmark time integration scheme to solve my problem. I have a bae
clamped at one end and under tensile at the other end. when I decrease
my time step ,at the beginning of the loading I see tiny negative
strains which is so weird. I used some numerical damping with the scheme
and I could reduce the time step but still I have this problem in
smaller time steps. Can anyone help me with this?
Thank you very much!!!
