When a weak incident shock wave strikes a wedge and Mach reflection takes place, the previous experimental values of the angle of reflection, the triple-point trajectory angle and so on disagree with the values predicted by the three-shock theory. This contradiction is known as"von Neumann's paradox"and this phenomenon is not yet fully understood. In this paper, the three-shock theory is examined and modified taking the pressure condition and the curvature of a Mach shock into consideration. The result obtained by the present analysis shows good agreement with the previous experimental results.textapplication/pdfjournal articl
