Hello,

I have seen more than often discussions about accelerated rods, or spinning disks in relativity.

It is clear that the definition of a rigid body in relativity makes problem.

I wonder if there are some books or papers giving a complete theory for relativistic elasticity.

I have seen here and there elements of hydrodynamics or ideal fluids models or collapsing star models.

For something closer to a rigid body, is there anything to read?

Or is it a dream? (°)

Michel

(°) May well be a dream. If the strain is low enough it is maybe possible to find a frame where relativistic effects disappear. If the strain is high, the material would break anyway and an ideal fluid model would be appropriate!
