Betti's theorem, also known as the Maxwell-Betti reciprocal work theorem, was discovered by Enrico Betti in 1872. It states that for a linear elastic structure subjected to two different sets of forces, the work done by the first set of forces acting through the displacements produced by the second set equals the work done by the second set acting through the displacements produced by the first. The theorem is used in structural engineering to define influence lines and to derive the boundary element method.

Betti's theorem, also known as Maxwell-Betti reciprocal work theorem, discovered by Enrico Betti in 1872, states that for a linear elastic structure subject to two sets of forces {Pi} i=1,...,n and {Qj}, j=1,2,...,n, the work done by the set P through the displacements produced by the set Q is equal to the work done by the set Q through the displacements produced by the set P.
