Is there any way to model and analyze porous materials in any FEA package? I am investigating structural properties of NiTi foams using FEA.
Thank you Tarkes Dora.... Before asking this question, I had modeled the sample with required porosity on Pro-E and then I had a plan to import it in Ansys for analysis... Isn't it the right way to get results closer to experimental data?
yes I am working on a powder metallurgy component and pores are generated during sintering. In this way we can obtain required porosity. Generally pores are interconnected.
Dear Tarkes Dora, In DEFORM software, would I have to define the porosity percentage in a solid component or I have to model the pores or voids without any volume? because modeling a large number of voids in a component is very time consuming process. Attached is a snapshot of the model I created in Pro-E. I created voids without volume inside the component.
Yes, it is very laborious and that's why I want to find a software in which I just model a solid component and define it that it is, lets say, 65% porous. That would be very easy to analyze with different porosity percentages... However, I will try this in DEFORM and then inform you about any progress... Did you work on foams or porous materials?
DEFORM WILL GIVE GOOD RESULTS ONLY FOR RELATIVE DENSITY GREATER THAN 80 OR 85 %. YOU HAVE TO DEVELOP A USER ROUTINE FOR THE VALUES LESS
THAN 80 UPTO 40 % RELATIVE DENSITY AT THE MAX. BEST WISHES .
