software of interest to mechanicians
Hello friends
I have a question about analysis method in Abaqus.
I want study the progressive of elements failure in a truss structure to find which element fail at first and which one fail after that while whole of the structure collapses.
Which kind of analysis method I could use?
Thanks a lot
I need to do a crash simulation in Abaqus, but i`m really new to this software. My material is aluminum and it is square column shape. Anyone can help me show the step to do the simulation.
Hi
iMechanica,
For my
graduation project I need to model the cracking behavior of a concrete beam in
bending (To simulate delamination of Steel Reinforced Polymer).
However I’m
relative new to FEM, I’m using Abaqus 6.10 (and have 6.11 available).
To get used
to the modeling of cracking behavior I started with a simple example, as described
in:
Alfaro, M.
Suiker, A. (2010) Transverse Failure Behavior of Fibre-epoxy Systems, Journal
of Composite Materials, Vol. 44, No. 12/2010.
Hello every body
i need constitutive law for an ortotrhtopic material for plane strain condition for 90 degree layups.
i derived it from 3D constitutive law equation from below formulation
S = [T2]^-1 [C] [T1]
which C are stiffness matrix, T2 and T1 are transformation matrix
i need this equation for stress-strain behaviour at thickness direction (x-z plane) but my results dosent agree with ansys sofwtware
could any body help me, plz?
Hi all,
I am stuck with a problem while starting to learn programming UEL in FEAP.
As a starting point, I programmed Isotropic Linear Elastic element (3D 8 node linear interpolation/shape functions), with one-point integration.
Before running this UEL, I wrote a simple 8 element input file and used FEAP standard Solid element (ELAStic, ISOtropic), the results for this input file were nice.
However when I ran the analysis for this input file with my UEL (USER 04), the displacements were unbelievable (x10^16).
Hello,
I understand from word of mouth, as well as an extensive study/Master'sThesis (http://publications.lib.chalmers.se/records/fulltext/164269.pdf), that Abaqus XFEM formulation works, but that processing of results to obtain reported SIF (KI, KII, KIII, not sure about J, others) are in error due to apparent bugs in Abaqus's algorithm to calculate the SIFs.
Hi
my problem is to define initial value for solution dependent state varibales in Vumat.when I define them in .log file the same as help,it doesn,t work and the error is your'e defining initial condition for element zero while this elemet doesn,exist.what can I do for solving this prolem.
thanks alot

Hi friends
I want to define a moving force with a special velocity in Abaqus, like a train force on a bridge.
Is it available in Abaqus ? If yes how I could define it?
Thanks
Pordon me if i couldn't reach my intention correctly.
You know that I have the functional dependence. For every elastic plastic property I have its termal function.
for example:
E=E(T), NU=NU(T), Syield=Syield(T).
But my question is that is it correct to define:
T=temp
and then
write Those function as props
Props(1)=E(T), etc.
or I ought to dedine the properties at several temprature separately and then define the strains and stresses respectively??
for example:
at T=T0
