在文献[1]中，我们提出了一个适用于生物组织的有限变形纤维增强材料的本构模型。该复合材料被假定为是由一个均匀的基体，其中可延伸的纤维嵌入。此外，它被假定为矩阵和一维纤维是超弹性的。因此，复合材料的应变能函数被假定为存储在基体中的能量加上存储在纤维中的能量的标量和，所有每单位的初始volume.In这里，一个薄的复合材料片的有限变形检查，以研究上述本构模型预测的纤维诱导的材料行为。具体来说，我们证明了（1）如何与线性性能的纤维可以诱导整体的非线性响应，和（2）由于有限变形的纤维重新取向的一些后果。
In a previous paper [I], we presented a constitutive model for finitelydeformed fiber-reinforced materials applicable to biological tissues. The composite was assumed to be composed of a homogeneous matrix in which extensible fibers were embedded. Furthermore, it was assumed that both the matrix and the one-dimensional fibers were hyperelastic. Consequently, the strain-energy function for the composite was assumed to be the scalar sum of the energy stored in the matrix plus the energy stored in the fibers, all per unit initial volume.Herein, the finite deformation of a thin composite sheet is examined in order to study the fiber-induced material behavior predicted by the aforementioned constitutive model. Specifically, we demonstrate (I) how fibers with linear properties can induce overall nonlinear response, and (2) some consequences of fiber reorientation due to finite deformation.
