pressure vs displacement in radioss block

Dear All,

 

could you please tell me how can i get a specific displacement whenever i apply pressure inside the cylinder in radioss block?

 

i mean how can i stop applying pressure at specific displacement?

 

example:

when i apply pressure inside cylinder i don't know how much deformation i get.

i give X amount of pressure and i want displacement 1 mm and after that displacement the cylinder will goes to the initial diameter(0.5 mm) after some time.i want specific displacement at X amount of pressure.

 

could you please tell me how to apply displacement sensor in radioss block?

can i use this displacement sensor in this application?

is there any other way to get specific displacement when we apply pressure inside the cylinder in radioss block?

 

Thanks a lot.....

 

Best Regards,

Bhautik

    is your calculation static or dynamic? i think your problem changes to dynamic as your pressure input will vary with the time after adding the sensor. Instead of using sensor maybe you can give your pressure as a function of time and check the time when the deformation is 1 mm then you can cut the pressure at that time in your function input.

    thank you very much for help.

    but it take lots of time for solution.
