[Radioss] how to set material for a solid model using PROP/Type

Hi all there

 

I have a question which I would like to ask you about how to solve. 

Problem: create an analyzing model (3 layers model) by using prop/type22 and calculate it. Then compare the result with the result of prop/solid/1

 

for example: A model which have 3 layers (sandwich layer) have the detail as follow:

t1 = 0.1, Young modulus1 = 3000 MPa

t2 = 0.8, Young modulus2 = 20000 MPa

t3 = 0.1, Young modulus3 = 3000 MPa

and calculate 2 cases (the result should be the same)

case 1: use prop/type22 to set 3 layer one

case 2: use prop/solid/1 and use the mean value of young modulus = 11700 MPa

 

thank you in advance!

    Hi,

     

    You can select the material for individual layers,

     

    Is this what you are looking for?

    Hi

     

    Thank you very much for your answer.

    I mean i don't know about the meaning of parameters of prop/type22 and how to set it by using editor (not the way to use hyperworks)

    could you please take a look at those file as I have attached?

    I don't know whether my setting is correct or not.

    HI,

     

    Looks good. I would suggest you to compare the same with the example for PROP/TYPE22 which is available on Radioss help

    could you please tell me the formula of calculating 3 values of young's modulus to the mean value of young's modulus of this model (by using prop/type22)? because the value of displacement when I calculated (in the case of E = 3000, 1 layer, prop/solid) is smaller than the result of 3 layers.

     

    And besides, could you please tell me the way to check the result of each layer? because the function Layers in Hyperview has been grayed out.

    HI,

     

    Unfortunately, I couldn't find any formulae for the type 22 property.

     

    Results by ply are work in progress for the same and should be available soon.
