| Abstract: | A new reflection wave method is presented for inspecting the pile integrity of the non-linear elastic material under the condition of low strain.Firstly,a new one-dimensional model of the pile of non-linear elastic material is set up; secondly,the dynamic equation of controlled body is given;thirdly,the relationship between the axial force and the axial strain is derived by using the non-linear elastic constitutive equation of one-dimension;finally,a new method is presented for the one-dimensional wave prop... |
