Elastic Foundation Stiffness

Elastic Foundation Stiffness

Elastic Foundation Stiffness

(OP)
Dear All,

I am doing a final project to design a mounded LPG bullet and found a problem to assign the elastic stiffness based on EMMUA.

There are 2 design conditions require to be considered which are consist of Subgrade Modulus 1 and Subgrade Modulus 2. The vessel rest on the soil only and elastic foundation is the suitable for my case.

The problem right now is when i assigning the elastic stiffness on the below surface of the vessel, there is no reaction force value come out. I am not sure whether im doing it in the correct way or vise versa. Trying to lookup in the Ansys help, but not get any much help on it.

Hope you guys can give me a light on this.

Regards

Hi,

If you are using Ansys Mechanical, insert a force reaction probe and scope it to the elastic foundation boundary condition. What kind of load are you subjecting the structure to?

Thanks for replying Petb...

I have done it by insert probe, and select elastic boundary condition, but there is no value in the reaction force and moment. i'm not sure if i am missing something.

I applied a force on top, and there's should be reaction force at the bottom. The image is as follows;



But, im not able to come out with any value in reaction force. Image as follows;
