Distribution of radial stresses σR along the radius r of the cylindrical cell for a total composition of 
 = 80 % axial orientation after a positive temperature step of 1 K. The numerical value of the in-plane elastic modulus Ep was set to 5.0 kN mm−2. σR,max indicates the absolute maximum radial stress and σR,max* represents the minimal maximum radial stress
