  To understand general properties of creep failure with healing effects, we
study a fiber bundle model in the mean-field limit with probabilistic rupture
and rejoining processes. The dynamics of the model is determined by two
factors: bond breaking and formation of new bonds. Steady states are realized
due to the balance between breaking and healing. Fluctuations around steady
states are jerky, characterized by a power-law statistics. Transient behaviors
also involve a power law with a non-universal exponent. Steady states turn to
meta-stable states if the healing process occurs only for finite times.
