Structure: Cylindrical structure
element type : solid element

Material : MAT24
Loading condition: Define displacement in the radial direction or in the normal direction of the segment of the solid element

I wonder how to define the above load among ls-dyna keywords.

Hello,

You have to create a displacement at each node with its own direction vector (*DEFINE_VECTOR). This is automated in LS-PrePost using the Entity Creation; it will create all the *BOUNDARY_PRESCRIBED_MOTION_NODE and *DEFINE_VECTOR automatically:

You will find more information here:

And here is an example model:
