Laser-driven, impulsive load shock wave in plane, solid aluminium layers are investigated by hydrodynamic simulation, using a realistic equation of state. With a 1.0 E15 W/cm2 laser pulse 30 ps long, a shock path X(f)=A.t(alpha) is found with alpha=0.73, inconsistent with similarity solutions for this problem. It is shown that alpha depends most strongly on the cold pressure components. Self-similar solutions require that the thermal pressure becomes much larger than the cold one.
