“…On the other hand, a parallel is provided in electrical systems by a leaky capacitor, which is neither a fully conservative ideal capacitor, nor a completely dissipative pure resistance. Modelling of the leaky capacitor and the visco-elastic material run along parallel lines, constructing equivalent circuits or networks with the ideal systems in series or parallel combination [28][29][30]. A more elegant approach is to introduce elements obeying laws involving derivatives (or integrals) with fractional order.…”

Desiccation crack formation is an important and interesting part of the broad area of fracture mechanics. Generation of cracks due to drying depends on ambient conditions, which may include externally applied fields. In this review, we discuss the effect of both direct and alternating electrical fields on desiccation crack formation. After a brief introduction to materials which crack on drying, e.g. colloids, clay and ceramics we discuss how they respond to an electric field. Following that, we present an account of experiments and modelling studies performed on granular pastes or clays drying while exposed to an electric field. Specific patterns formed under different geometries, strengths and frequencies of the electric field are described and explained. The review includes work on cracks formed in clay droplets, where a memory effect has been observed and analysed using a generalized calculus formalism. This article is part of the theme issue ‘Statistical physics of fracture and earthquakes’.
