This paper deals with the experimental study on thin-walled cylinder of finite length subjected to hydrostatic internal pressure and axial load. Annealed aluminium, copper and 70/30 brass tubes are used. The outside diameter of these tubes is 40 mm and the wall thickness is 1 mm. Experimental results such as strain distribution, relation between the internal pressure and the center radius, bursting pressure, critical expanding radius (radius at the center of the cylinder when it bursts), etc. are obtained. These results are compared with the analytical ones by the strain incremental theory (2nd Report) and the logarithmic total strain theory (1 st Report). In general, the experimental results agree with the analytical ones by the strain incremental theory except for the critical expanding radius of short cylinders.
