Inclusion of intertial forces requires the specifica-

u(x, 0) = d0(x) (4.18)
u̇(x, 0) = v0(x) (4.19)
where d0 is the initial displacement field, and v0 is the initial velocity field.

The linear theory is completed by specifying节选段落三：

hand, the Hellinger-Reissner principle is an important limiting case when considering
problems with constraints (e.g., linear elastic incompressible problems, thin plates as
a limit case of the thick Mindlin-Reissner theory).
