生长软组织的形态发生

Morphogenesis of growing soft tissues

Julien Dervaux, Martine Ben Amar

摘要:

最近,人们对一些软组织的一个值得注意的特性给予了很大的关注:它们的生长能力。在生物学、化学和物理学中,已经进行了许多尝试来模拟这种行为。利用有限弹性理论,Rodriguez假设几何变形梯度的乘法分解为生长诱导部分和确保物体相容性所需的弹性部分。为了充分探讨这一假设的后果,薄弹性物体有限增长下的方程推导。在适当的缩放假设的增长率,所提出的模型是Foppl-von Karman型。作为例子,研究了自由超弹性圆盘的周向增长。

英文摘要:

Recently, much attention has been given to a noteworthy property of some soft tissues: their ability to grow. Many attempts have been made to model this behaviour in biology, chemistry and physics. Using the theory of finite elasticity, Rodriguez has postulated a multiplicative decomposition of the geometric deformation gradient into a growth-induced part and an elastic one needed to ensure compatibility of the body. In order to fully explore the consequences of this hypothesis, the equations describing thin elastic objects under finite growth are derived. Under appropriate scaling assumptions for the growth rates, the proposed model is of the Foppl-von Karman type. As an illustration, the circumferential growth of a free hyperelastic disk is studied.
