Abstract

The Lagrangian function of self-gravitating spherically symmetric matter shells composed of an elastic fluid is derived from variational principles in the General Relativistic context. The natural Hamiltonian of the system, representing the total energy for a distant observer, is then calculated in terms of canonical variables. Known results for the dust case can be recovered.
