Determination of pressure-dependent friction coefficient from draw-bend test and its application to cup drawing

► Press distribution in draw-bend test is analyzed to obtain a pressure and direction dependent friction law. ► The proposed anisotropic friction law is implemented into a commercial finite element code. ► Cup drawing experiments are conducted for assessing the proposed friction law. ► Cup drawing simulations using the friction law reveal differences in flange draw-in in two directions. ► Simulations and experimental data reveal good agreement and the friction law has other applications.
