The time-dependent response of a surfactant hexagonal phase of a sodium dodecyl sulphate/pentanol/cyclohexane/brine system to stepped strain is investigated. The dynamics of the system is found to be governed by strain- and noise-induced yielding of the domains of the system. The effects of the applied strain magnitude and the ionic strength of the brine on the character of the transitions experienced by the system are reported.
