Hi

Has anyone followed the book Inelasticity of Materials by Arun Srinivasa?

I was interested in the way he used lumped parameter models to describe material behaviour in Chapter 3. Trying to follow his methodology I wanted to implement it for some experimental results I have.

However, I have faced an obstacle in trying to work out the hardening modulus of the the material in question. He has worked it out for his example case by curve fitting but I am just not getting the answer.

## Question about Smeared Crack models

Hi, I want to ask you guys about how to model an unconfined conrete material with smeared crack model in abaqus 6.10, especially about what kind of parameter should I use and how much the value of parameter. I would really appreciate if you could give me some tutorial, explanation, or even an example of how should I model a smeared crack model in abaqus.

Thanks.

## How to give an Impact loading in ANSYS workbench static structural

Hi,

Can any one know the way to give and impact force in  ANSYS workbench static structural ?

Thanks

## modelling and analysing the laminated composites in ANSYS 14.5

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

## MWR for the first- and third-order differential equations

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?

## BENDING MOMENT DIAGRAM IN ABAQUS

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?

## Buckling analysis of a imperfection sensitive cylinderical shell under compression

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

## CAE

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?...

## How to set the parameters of ductile damage in ABAQUS?

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.

## low reynolds number flow over a capsule in fluent

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/m

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?
