论文摘要
我们为特殊的cosserat棒提出了一个生长模型，该模型允许引起横截面的旋转。生长法考虑了两个控件，一个用于纵向增长，另一个用于旋转。通过引入对称性保留生长以说明微观结构的对称性，可以更详细地探讨这一详细介绍的直杆。具有手性微结构的引导引导杆的例子被认为是研究其由于生长而导致的变形。我们显示了这种棒中生长引起的平面外屈曲的发生。
We present a growth model for special Cosserat rods that allows for induced rotation of cross-sections. The growth law considers two controls, one for lengthwise growth and other for rotations. This is explored in greater detail for straight rods with helical and hemitropic material symmetries by introduction of a symmetry preserving growth to account for the microstructure. The example of a guided-guided rod possessing a chiral microstructure is considered to study its deformation due to growth. We show the occurrence of growth induced out-of-plane buckling in such rods.
