The practical force is identified using the combination of the principal stresses from the analytical and empirical method with analyzed strain by F.E. Analysis under unit load and with measured strain by strain gages under driving load, respectively.<br/>
The procedure of practical force identification is theorized with inverse problem. Theory and practice do not always coincide: since there arc some errors such as ill-poseness measuring error in experimental data and modeling error in F.E. model. The regulari71ltion method is adopted to reduce these errors.<br/>
To examine the proposed method, finite element analysis and experiment are conducted to T-shaped joint. Model for finite clement analysis is achieved by MSC.PATRAN80 and is analyzed by MSC.NASTRAN70.5.<br/>
