a = 50 //mm - length of a cube
E = 200 // GPa - the youngs modulus

//pressure is a compressive stress

S_y = -200 // GPa - The stress in Y direction
S_z = -200 // GPa - The stress in Z direction
//calculations
e = S_x*(10**-3)/E - v*S_y*(10**-3)/E-v*S_z*(10**-3)/E//mm - considering all three directions
x = e*a //mmThe change in the dimension between parallel faces
