Influence of the Metal Sheet Parameters on the Results of the Erichsen Test
Considering an isotropic rheological law of the sheet material and the power law relationship between the stress and the plastic strain, the present paper by using the finite element method analyzes the influence of the material parameters on the results of the Erichsen test in terms of force-displacement curve of the punch and the normalized thickness measured at the specimen apex also varying the coefficient of the Coulomb friction law. Moreover for an AA5083 aluminum alloy the results of the numerical simulation of the Erichsen test will be compared to those obtained experimentally.
