我们已经开发了一种方法来测量纤维运动学在二维软胶原组织。该技术结合了小角度光散射（SALS）和双轴拉伸控制的同时光学应变测量。对猪主动脉瓣叶和牛心包的初步研究结果表明，纤维运动学具有高度的组织特异性，并且通常是非仿射的。每个组织内纤维的移动性似乎是专门执行不同的生理功能。定量了解组织的角纤维分布及其在双轴拉伸过程中的变化对于平面组织的微观结构建模至关重要。我们的研究结果强调了测量每种特定组织类型的纤维运动学的重要性。(C)1997年爱思唯尔科学有限公司
We have developed a method for measuring fiber kinematics in two-dimensional soft collagenous tissues. The technique combines small-angle light scattering (SALS) and biaxial stretch controlled by simultaneous optical strain measurement. Preliminary findings on porcine aortic valve leaflets and bovine pericardium indicate that fiber kinematics are highly tissue specific and are generally non-affine. The mobility of the fibers within each tissue seems to be specialized to perform a distinct physiological function. Quantitative knowledge of a tissue's angular fiber distribution and its transformation during biaxial stretch is critical for microstructural modeling of planar tissues. Our results underscore the importance of measuring fiber kinematics for each specific tissue type that is to be modeled. (C) 1997 Elsevier Science Ltd.
