In elastic-wave turbulence, strong turbulence appears in small wave numberswhile weak turbulence does in large wave numbers. Energy transfers in thecoexistence of these turbulent states are numerically investigated in both ofthe Fourier space and the real space. An analytical expression of a detailedenergy balance reveals from which mode to which mode energy is transferred inthe triad interaction. Stretching energy excited by external force istransferred nonlocally and intermittently to large wave numbers as the kineticenergy in the strong turbulence. In the weak turbulence, the resonantinteractions according to the weak turbulence theory produces cascading netenergy transfer to large wave numbers. Because the system's nonlinearity showsstrong temporal intermittency, the energy transfers are investigated at activeand moderate phases separately. The nonlocal interactions in the Fourier spaceare characterized by the intermittent bundles of fibrous structures in the realspace.
