Hello there,

Please guide me with what CARD should I use if I want to give properties to sand.
Is MAT1 correct option to go with?
thank you

Hi Surya,
What properties do you have and what is the simulation about?
Hi Prakash,
Actually I am doing a crash simulation when a car hits a highway guardrail, the rods of which are buried in the ground up to a certain height.
Hence I needed the contact type between rod material and ground (here sand).
I have the density & poisson's ratio.
Actually now I realized I have by mistake put my query in Optistruct query stream, I am doing it in Radioss, sorry for that.
Thank you
Please have a look at LAW 21 for sand.
thank you,
I will try it out
Hi,
I have worked on security bollards which is similar to this. I my case I had concrete foundation which is made by digging a pit and then pouring concrete
Are the guard rails also in the concrete and then we have an interface with sand?
For concrete: MAT LAW 24 will work and for sand MAT LAW 21 can be used.
