Forming limits evaluation
Biaxial tensile test at room temperature
Biaxial tensile tests using optimised cruciform speciments permit the measurement of linear and non-linear strain paths at room temperature, at quasi-static conditions or at high deformation rates. The straith path can be controlled by the displacement of the machine, using DIC system with 3D calibration.
Deep drawing test
This test helps to predict the critical points in real stamping components and can be used for the optimisation of deisgned die, fast acceptance inspection for new sheet/coil, FEM verification and providing a complex view of formability (relation between stress and strain state).
