Abstract
By vibrating pastes before drying, we can control the morphology of crack patterns that appear in the drying process. The experiments show a transition in the direction of lamellar cracks from perpendicular to parallel when compared with the direction of the initial external vibration as the solid volume fraction of paste is decreased. The transition in the crack patterns is induced by the transition of memory in paste from memory of vibration to memory of flow. Using the memory effects, it becomes possible to control and produce various crack patterns, such as cellular, lamellar, radial, ring, spiral (Fig. 1), and others.
