I WANT TO find the flexural strength of laminated composites after it is subjected to cyclic loading

i have to use the output of the cyclic loading as the input to find the strength

i want to know the procedure for that

please help me out

Hi all,

In engineering sciences, we usually end up using either the second- or the fourth-order differential equations, and the MWR (the method of weighted residuals) works pretty well for them.

The question is: how about the first- and the third-order differential equations? Why don't we see any applications of MWR for these odd-ordered differential equations? What gives?

I have created a channel beam using 3D shell elements. It is subjected to two point loading each at 1/3rd length. I have performed STATIC RIKS analysis. Is it possible to draw bending moment diagram for this model? Orelse if i use section moments how can i interpret the maximum moment?

Your reply is highly appreciable.

I have carried out eigen buckling analysis of cylindrical shell under axial compression under unit load  using abaqus in model-1 and in model -2 i carried out riks analysis gave imperfection 0.2mm fotr shell thickness 2mm radius 0.25m,h=0.5 m after the 100 increment the the shell is subjected to load which is obtained from first buckling load in first mode  here how to get the collapse load

hi im prasath now im a CAE trainee. i want to know more about CAE analysis what are the necessary things i've to learn and experienced in this field?...

Hi,




I want to try abaqus ductile damage model to simulate steel
failure in Abaqus. I read the manual, and have some ambiguities regarding its parameters.

 Is there somebody to have experiences in ductile damage to share?

Thanks.

I've been trying to simulate flow conditions at 100 km altitude over a re entry capsule in fluent.

Conditions are

Temperature:
168.7219
K

Density = 0.000000577 Kg/m³

Pressure = 0.0289 N/m² 

I tried using laminar and k-w model. The solution does not converge even after 50000 iterations using the density based solver and ideal gas equation.

Is there a way to go about it?

Please let me know.
