这份报纸探索生长在生物软材料的导致的词法不稳定性。鉴于生活纸巾的生长不仅改变它的几何学而且罐头改变它的机械性质，我们建议在材料的机械性质上合并生长的效果的一个精制容量的生长模型。在这个容量的生长模型和常规热压力模型之间的类比为小、有限的变丑问题被探讨，它基于建议模型为有限元素分析带大容易。导致的生长的例子出现起皱在软 composites 的行为，包括核心壳软柱体和三分层的软纸巾，被探索。结果和讨论在理解在软生物纸巾的形态发生和生长之间的关联预见模型的可能的应用(例如皮肤和肿瘤) ，以及在评估，变丑和软人工的材料的表面不稳定性行为由 swelling/shrinkage 导致了。

英文摘要：

This paper explores growth induced morphological instabilities in biological soft materials. In view of that the growth of a living tissue not only changes its geometry but also can alter its mechanical properties, we suggest a refined volumetric growth model incorporating the effects of growth on the mechanical properties of materials. Analogy between this volumetric growth model and the conventional thermal stress model is addressed for both small and finite de- formation problems, which brings great ease for the finite element analysis based on the suggested model. Examples of growth induced surface wrinkling behavior in soft composites, including core- shell soft cylinders and three-layered soft tissues, are explored. The results and discussions foresee possible applications of the model in understanding the correlation between the morphogenesis and growth of soft biological tissues （e.g. skins and tumors）, as well as in evaluating the defor- mation and surface instability behavior of soft artificial materials induced by swelling/shrinkage.
