大腦 BRAIN

大腦是脊椎動物頭骨中的一種軟組織。它是高度異質性的，因為它包含白質和灰質，它們具有不同的力學行為。常用的腦組織測試方法有動態剪切、拉伸、壓縮和壓痕。可以用機械方法測試大腦的體積特性，也可以在單獨的樣本中進行腦組織的結構建模。需要對腦組織的機械特性有全面的了解，才能將組織的機械反應與實際損傷聯系起來。此外，有關組織特性的準確信息將允許對腦組織模型進行有限元分析。對大腦進行機械測試，以了解其對損傷、手術和病理學的反應。此外，需要測量腦組織的機械特性，以幫助開發自動化手術工具、機器人和外科醫生培訓系統。

BRAIN
Brain is a soft tissue contained in the skull of vertebrates. It is highly heteregenous because it contains both white and gray matter, which have different mechanical behaviors. Commonly used test methods for brain tissue are dynamic shear, tension, compression and indentation. Brain can be mechanically tested for bulk properties or in separate samples for constitutive modeling of brain tissue. A complete knowledge of the mechanical properties of brain tissue is needed to relate the mechanical response of the tissue to actual damage. Also, accurate information about tissue properties will allow implementing finite element analysis of brain tissue models. Mechanical testing of brain is performed to learn about its reaction to injury, surgery and pathologies. Moreover, accurately measured mechanical properties of brain tissue are needed to aid in the development of automated surgical tools, robots and surgeon training systems.
