“…Thus, simple experiments in one domain, such as drying clays [83] or starch [84], can be used to provide insight into more challenging questions in the other domain, such as how permafrost responds to seasonal temperature variations [82], or how lava breaks as it cools [87]. Some examples of such related patterns are shown in fig.…”

Abstract. The drying of complex fluids provides a powerful insight into phenomena that take place on time and length scales not normally accessible. An important feature of complex fluids, colloidal dispersions and polymer solutions is their high sensitivity to weak external actions. Thus, the drying of complex fluids involves a large number of physical and chemical processes. The scope of this review is the capacity to tune such systems to reproduce and explore specific properties in a physics laboratory. A wide variety of systems are presented, ranging from functional coatings, food science, cosmetology, medical diagnostics and forensics to geophysics and art.

“…The two types of cracks can be differentiated in a visual way 2,34,38 . Primary cracks appear successively and they typically meet at T-shaped junctions, since a later crack will preferentially meet an earlier one in a normal direction.…”

“…Examples include those that develop in dried mud [1][2][3] , old paintings 4,5 , ceramic glaze 6,7 , and so on. These cracks usually exhibit a specific network structure, splitting the entire surface of the fractured media into many polygonal cells.…”

Morphometric analysis of polygonal cracking patterns in desiccated starch slurries

We investigate the geometry of two-dimensional polygonal cracking that forms on the air-exposed surface of dried starch slurries. Two different kinds of starches, made from potato and corn, exhibited distinguished crack evolution, and there were contrasting effects of slurry thickness on the probability distribution of the polygonal cell area. The experimental findings are believed to result from the difference in the shape and size of starch grains, which strongly influence the capillary transport of water and tensile stress field that drives the polygonal cracking.

“…They are observed during the desiccation of films made of colloidal suspensions, like bentonite clay or cornstarch [5][6][7][8][9][10][11], in sol-gel films [12,13], in broken objects like windows [14][15][16], or in sea ice [17,18] and ice floes collisions [19,20].…”

We study the interaction between two cracks propagating quasistatically during the tearing of a thin brittle sheet. We show that the cracks attract each other following a path described by a power law resulting from the competition between elastic and fracture energies. The power law exponent (8/11) is in close agreement with experiments. We also show that a second (asymptotic) regime, with an exponent of 9/8, emerges for small distances between the two crack tips due to the finite transverse curvature of the elastic ridge joining them.
