Conditions of existence of triple-shock configurations with normal main (Mach) shock (so-called stationary Mach configurations) in the presence of pulsed energy absorption on that strong main shock are determined analytically and numerically. As formation of stationary Mach configuration corresponds to well-known von Neumann criterion, which describes Mach/regular oblique shock reflection transition, shift of that criterion due to possible flow endothermicity at the main shock is estimated. Keywords: steady shock wave, triple-shock configuration, regular reflection, Mach reflection, von Neumann criterion.
