摘　　要：A multisymplectic variational internal energy corresponding equation, its associated local framework for the nonlinear elastic wave equation is presented. The modified to the approximate nonlinea.r elastic wave equation is derived, we obtain the energy and momentum conservation laws as well as the multisymplectic form simultaneously directly from the variational principleA multisymplectic variational internal energy corresponding equation, its associated local framework for the nonlinear elastic wave equation is presented.
