Remarks on nonlinear elastic waves in the radial symmetry in 2-D
In this paper, we first give the explicit variational structure of the nonlinear elastic waves for isotropic, homogeneous, hyperelastic materials in 2-D. Based on this variational structure, we suggest a null condition which is a kind of structural conditionon the nonlinearity in order to stop the formation of finite time …
