| Abstract: | Conditions and method for constructing stiffness distribution function of various parameters symmetric simple supported beams with a symmetric or anti-symmetric mode and specified polynomial density distributing function are discussed. It is shown that the constructed stiffness distribution functions are positive functions in case with different density distributing. Two numeral examples are given. And two problems correlated are explained. |

| Keywords: | single mode simple supported beam symmetric property inverse problems |
