We present a new analytical solution for the finite extension and torsion of a nonlinearly pseudoelastic, homogeneous, transversely isotropic, incompressible, solid circular cylinder. This solution can be used to guide the performance and interpretation of experiments, and to identify a specific functional form of a three-dimensional constitutive relation directly from data. We submit, therefore, that this solution can be used by experimentalists to quantify the multiaxial constitutive relations, including shear, of both passive and tonically activated papillary muscles for the first time.
我们给出了一个关于非线性伪弹性、均匀、横观各向同性、不可压缩的实心圆柱体有限拉伸和扭转的新解析解。该解可用于指导实验的性能和解释，并直接从数据中识别三维本构关系的特定函数形式。因此，我们认为实验人员首次可以使用该解来量化被动和张力激活的乳头肌的多轴本构关系，包括剪切关系。
