摘要：
The three-dimensional model of the hyperelastic body under large strains is researched. A new strain measure, based on the QR-decomposition of the deformation gradient, is discussed. It is shown that this strain measure allows for more explicit analytical connections between different parameters of the stress-strain condition then the traditional approach. An example method of introducing this measure into numerical simulations for an arbitrary three-dimensional model with linear shape functions is presented.
