气动表面中通过弹性相分离的形态发生
Morphogenesis through elastic phase separation in a pneumatic surface
摘要:
我们报告的现象相分离,涉及在许多方面Yves Couder的工作:一个可膨胀的建筑弹性体板,预计在其平面内均匀膨胀,而不是广泛的平面外非常复杂的形状时,施加内部压力。我们表明,这种形态发生斑图形成是由于一个二维弹性相分离,这导致不兼容的补丁非欧几里德参考度量。
英文摘要:
We report a phenomenon of phase separation that relates in many aspects to Yves Couder's work: an inflatable architectured elastomer plate, expected to expand homogeneously in its plane, buckles instead widely out-of-plane into very complex shape when internal pressure is applied. We show that this morphogenetic pattern formation is due to a two-dimensional elastic phase separation, which induces incompatible patchy non-Euclidean reference metric.
