can we model semi rigid joint in abaqus if yes can any one please give me a hint how to model the semi rigid joint..

i am new in using abaqus and also in materials analysis fatigue

so i want to use stress ratio R=-1 and R=0 for analysis an aluminium material

so how to define this in abaqus

is it to take in amplitude (periodic) and define A₀ and t0 w also the values of A B? IS THIS CORRECT OR NO

thank you 

Hello everyone,

I want to know about extended beam Theory.

Can you help me please about this theory?

Best regards

All,

i`m want to know how deaccelerated load for transient analysis.first load strat accelerated move till mid point of beam after that deaccelerated.for second part please help me

hello

i have a problem,i am trying it about one years

is:aeroelastic blade of helicopter with abaqus

i find some method for solution:

1.using abaqus for 2D ANALYSIS of cross section(meshed cross section) and then  1D  modal analysis modal,then using ZAERO for aerodynamic load,my problem in case is:linking abaqus and zaero.what is solutin method?

I am trying to use material model 58 of ls dyna to simulate a drop tower test on a carbon fibre epoxy composite. However i am getting poor simulation results with very high eroded internal energy values for composite.  My parameters are as follows

Hollow composite cylinder (with quad shell elements) of thickness 5mm with a mass of about 120g.

Impactor of weight 82 kg with impact vel of 6 m/s (direction along the longitudinal of composite cylinder)

material model in ls dyna : MAT 58
