| Remarques | (1) it provides a large hot spot (up to 3 cm) with a quasi-inexistent
thermogradient and a temperature sensitivity of +/- 1°C, (2) it is able to hot press large samples (up to 2 cm3), (3) it performs high resolution deformation experiments in both constant load and constant displacement modes (4)experiments under controled pore fluid pressure. |
