Continuum-mechanical Forward Simulation Results of a Human Upper-limb Model Under Varying Muscle Activations

This dataset provides simulation results from a high-fidelity human upper-arm finite element model under varying muscle activations and an example script to load the data. The upper arm model consists of the bones of the radius and ulna for the forearm and the humerus for the upper arm. The elbow joint that connects them is modeled as a simple hinge joint. It contains five muscles that operate this joint, two extensors and three flexors: m. triceps brachii m. anconeus m. biceps brachii m. brachialis m. brachioradialis The geometry of all these components is modeled after the Visible Human Male dataset. Each of the muscles is associated with a corresponding muscle activation, which represents the percentage of the maximum possible active stress that the muscle is currently exerting. The provided simulation results themselves contain data on element- and node-level including positional data as well as stress data and node-connectivity information. The saved simulation results constitutes equilibrium states for the given activation levels.

本数据集提供了在多种肌肉激活程度下，基于高保真度人体上臂有限元模型所进行的模拟结果，并附带了用于加载数据的示例脚本。该上臂模型由前臂的桡骨和尺骨以及上臂的肱骨构成。连接这些骨骼的肘关节被建模为一个简单的铰链关节。模型内包含五个控制该关节运动的肌肉：肱三头肌、小指长伸肌、肱二头肌、肱肌、桡侧腕伸肌。所有这些组件的几何形状均参照《可见人类男性》数据集进行建模。每个肌肉均与相应的肌肉激活度相关联，该激活度表示肌肉当前施加的活性应力与最大可能活性应力的百分比。所提供的模拟结果本身包含元素级和节点级的数据，包括位置数据、应力数据和节点连接信息。保存的模拟结果代表了在特定激活程度下的平衡状态。
