Abstract
A new fast variation method (FVM) for determining an elastic strip response to stresses arbitrary distributed on the flat side of the strip is proposed. The remaining surface of the strip may have an arbitrary shape and it is free of stresses. The FVM, as well as the well-known finite element method (FEM), starts from the variational principle; however, it does not use the meshing of the strip. A comparison of FVM results with the known exact solution in the special case of shear stresses and a rectangular strip demonstrates an excellent agreement
