Evolution of polygonal crack patterns in mud when subjected to repeated wetting-drying cycles
Ruhul A I Haque, Atish J. Mitra, Sujata Tarafdar +1
The present paper demonstrates how a natural crack mosaic resembling a random tessellation evolves with repeated 'wetting followed by drying' cycles. The natural system here is a c…
Growth kinetics of NaCl crystals in a drying drop of gelatin: transition from faceted to dendritic growth
Moutushi Dutta Choudhury, Tapati Dutta, Sujata Tarafdar
We report a study on the kinetics of drying of a droplet of aqueous gelatin containing sodium chloride. The process of drying recorded on video, clearly shows different regimes of…
Topology of desiccation crack patterns in clay and invariance of crack interface area with thickness
Tajkera Khatun, Tapati Dutta, Sujata Tarafdar
We study the crack patterns developed on desiccating films of an aqueous colloidal suspension of bentonite on a glass substrate. Varying the thickness of the layer gives the fo…
Desiccation of a clay film: Cracking versus peeling
Supti Sadhukhan, Janett Prehl, Peter Blaudeck +3
Cracking and peeling of a layer of clay on desiccation has been simulated using a spring model. A vertical section through the layer with finite thickness is represented by a recta…
