在分析骨骼肌组织的大量工作中，相对较少的是在检查其被动材料特性方面。以往对骨骼肌被动特性的研究主要是沿沿着材料方向进行的。为了保证骨骼肌计算模型预测的准确性，更好地了解肌肉组织的拉伸三维材料特性是必要的。为此，本研究的目的是从骨骼肌组织中收集一组全面的拉伸应力-应变数据。从9只新西兰白色家兔的18块趾长伸肌收集载荷-变形数据，这些肌肉在纵向伸展（LE）、横向伸展（TE）或纵向剪切（LS）条件下进行试验。根据应力-应变结果计算线性模量、极限应力和失效应变。结果表明，LE下的线性模量显着高于TE或LS的模量。此外，肌肉的极限应力被认为是显着高于下LE比TE。相反，TE下的破坏应变显著高于LE下。
Of the plethora of work performed analyzing skeletal muscle tissue, relatively little has been done in the examination of its passive material properties. Previous studies of the passive properties of skeletal muscle have been primarily performed along the longitudinal material direction. In order to ensure the accuracy of the predictions of computational models of skeletal muscles, a better understanding of the tensile three-dimensional material properties of muscle tissue is necessary. To that end, the purpose of this study was to collect a comprehensive set of tensile stress–strain data from skeletal muscle tissue. Load-deformation data was collected from eighteen extensor digitorum longus muscles, dissected free of aponeuroses, from nine New Zealand White rabbits tested under longitudinal extension (LE), transverse extension (TE), or longitudinal shear (LS). The linear modulus, ultimate stress, and failure strain were calculated from stress–strain results. Results indicate that the linear modulus under LE is significantly higher than the modulus of either TE or LS. Additionally, the ultimate stress of muscle was seen to be significantly higher under LE than TE. Conversely, the failure strain was significantly higher under TE than under LE.
