The boundary element method is applied to the analysis of two-dimensional self-similar wedge entry problem, assuming that fluid is incompressible and inviscid, gravitational effects are negligible and impact velocity is constant. In order to solve the problem exactly, formation of splash is taken into consideration. The calcuration is carried out for cases of dead rise angle β=45°,30°,20°,15°,10°,8°,6°and4°. The shape of free surface with splash, the impact pressure distribution over the wedge and velocity vectors of the flow arround the wedge are calcurated and compared with Wagner's theoretical results and Hughes's numerical results as well as experimental results. It is concluded that the splash should not be neglected to estimate pressure distribution over the wedge correctly.
