Control of crack pattern using memory effect of paste [Invited]
12th Continuum Models and Discrete Systems   24 Feb 2011   
We find a method to control morphology of desiccation crack patterns by using memory effect of paste. Pastes made of powder and water remember the direction of external mechanical fields, such as vibration and flow. These memories in pastes are su...
