The experiments involve subjecting metal sheets to biaxial deformation, coupled with advanced measurement of Forming Limit Curve (FLC) diagrams using linear and non-linear strain paths.

The system is equipped with four independently controlled actuators with a total load capacity of 50 kN of each one. The innovative design allows a simultaneous strain tracking using a contactless optical DIC system on one side, complemented by thermographic measurements on the opposite side of the tested specimen.

The specimen loading can be controlled by actuator speed, in stress control mode or in strain control mode using the DIC system.
