Hello Nejib,
From a general point of view if we note 1(=axial for ex), 2,3 
(=laterals) the directions of the space, L1, L2, L3 the size of your 
specimen in these three directions, and v1, v2 and v3 the speeds at 
which you displace your walls in these three directions I would say that 
you will be at a constant volume if you keep v1/L1 + v2/L2 + v3/L3 =0
(No more stress control by this way, your test will be fully strain 
controlled)
