本文提出了一种新的骨骼肌建模概念。一个重要的方面是这个概念是微机械驱动的。在收缩肌纤维的水平上，我们将最小可能单位的行为纳入其中，即所谓的肌节，也称为微生物引擎。收缩纤维（材料的主动部分）被软组织网络（材料的被动部分）包围。一般来说，微机械方法的一个基本优点是可以显著减少材料参数的数量，并且通常可以物理地解释剩余的参数。所选择的建模策略使得能够将关于纤维中的生理过程的已知信息有效地传输到3D宏观水平，其中例如研究肌肉收缩对刺激速率的依赖性。本文结束调查的准静态以及动态模拟应用于理想化和非理想化的肌肉几何形状。
In the present paper, a new concept for the modelling of skeletal muscles is proposed. An important aspect is the fact that the concept is micromechanically motivated. At the level of the contractile muscle fibres we incorporate the behaviour of the smallest possible unit, the so-called sarcomere, also known as microbiological engine. The contractile fibres (active part of the material) are surrounded by a soft tissue network (passive part of the material). One fundamental advantage of micromechanical approaches in general is the fact that the number of material parameters can be noticeably reduced and the remaining parameters can be usually interpreted physically. The chosen modelling strategy enables the efficient transport of the known information about physiological processes in the fibre to the 3D macroscopic level where, e.g. the dependence of muscle contraction on the stimulus rate is studied. The paper closes with investigations of quasistatic as well as dynamic simulation applied on idealised and non-idealised muscle geometries.
