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

REGARDS

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

Dear ALL

I have this PDF and I have some information at this coding but have not information about the temprature dependent material properties.

what can I do??

sorry for that

For example see this function:

E(T)=E0*T^2+A*T+ ....

What can I define this type of Function?? 

Is my statement true? Can I do alike nonisotermal behaviour of the material???

 Please help me 

 Thanks so much

I'm using Abaqus in analysis of random vibration fatigue. I linked abaqus with fe-safe to calculate the fatigue life. Fe-safe didn't recognize the random load comming from Abaqus correctly, althghou it already recognize the cyclic(normal) load crrectly in one of the tutorial's attached example.

Do any body know how to solve this issue? 

Dear All

I have writed a elastoplastic VUMAT to analyse a model in abaqus explisit code but after the analysis was finished, i can not observe the plastic strain conutors in it, in the onther word there is not PE option at odb field output. I rewuest you to give a favor to me. I am confused

thanks 

The reliability of a gas or steam turbine is strongly
dependent on the blade structural design. 
Turbine blades are subjected
to very strenuous environments such as high temperatures, high stresses, and a
potentially high vibration environment. To avoid blade failures, they must be
designed to withstand these conditions. 

Dear all, I want to simulate forming process with abaqus, and extract the modal frequencies of the formed model. I mean two steps in a single model.  Is it feasible? Many thanks for your discussion and help.

i am currently doing project using ansys. i have to model the properties of a gel using viscoelastic properties. there are different viscoelastic models in ansys , i dont know which model should use and how we get the parameters for that model.hope a favourable reply

regards

hello

i simulted impact on ceramic plate but after the impact the element of
ceramic didnot erod. i use element deletation=yes, any body know what
should i do?

thanks

Dear Sir/madam

I am doing my master thesis using abaqus in area of structural dynamics. I am in need of help regarded with  how to apply internal pressure, torsional loading , shear loading in buckling of cylindrical shell structural analysis. Please help me in this regard

With warm regards

I WOULD LIKE TO LEARN ABACUS . KINDLY PROVIDE YOUR VALUABLE GUIDANCE.
