Abstract: Nonlinear pulsation driven by strange modes is investigated. Nonlinear simulations are carried out with the OP opacity for the models M=0.8 Ms, Teff = 6300 K. The luminosity is a controll parameter with the range of 1500-4000 Ls. It is shown that irregular pulsation with small amplitudes is realized for the models of higher luminosities. The nature of the irregular pulsation is examined with the fractal dimension analysis.
