| 摘 要： | Two-dimensional stress waves in a general incompressible elastic solid are investigated.First,basic equations for simple waves and shock waves are presented for a general strain energy function.Then the characteristic wave speeds and the associated characteristic vectors are deduced.It is shown that there usually exist two simple waves and two shock waves.Finally,two examples are given for the case of plane strain deformation and antiplane strain deformation,respectively.It is proved that,in the case of plane strain deformation,the oblique reflection problem of a plane shock is not solvable in general.
