Local force identification on flexural plates using reduced Finite Element models
The Force Analysis Technique using a local Finite Element Method is proposed. Free boundary conditions and dynamic condensation of non measurable DOFs are used. To deal with a high number of DOFs, a CraigBampton reduction option is proposed. The ability to reconstruct equivalent forces due to moments is discussed. General guidance, numerical and experimental results are given on plates.
