Strain rate sensitive properties of skin

软组织，如韧带、肌腱和皮肤，具有时间和历史依赖性的特性。尽管在实验和理论生物力学方面取得了许多进展，但这些软生物结构的材料特性仍然没有被很好地理解。我们的研究小组检查了软组织在高应变率下的反应。人体在各种情况下都会受到动态载荷，其中最常见的一种就是车祸。这个博士项目专注于开发理论和实验相结合的工具来捕捉软组织的应变率依赖行为。实验工作将包括在动态拉伸加载条件下(应变率大于100 1/S)测试皮肤。除了实验测试外，还将开发出准确描述观测到的应变率依赖关系的本构模型。其目标是开发考虑潜在组织形态的结构本构模型。

Soft tissues such as ligaments, tendons, and skin possess time- and history-dependant properties. Despite the many advances in experimental and theoretical biomechanics, the material properties of these soft biological structures are still not well understood. Our research group examines the response of soft tissues at high strain rates. The human body is subjected to dynamic loading in a variety of situations, one of the most common being automobile accidents. This PhD project focuses on the development of combined theoretical and experimental tools to capture the strain rate dependent behaviour of soft tissues. The experimental work will involve testing skin under dynamic tensile loading conditions (strain rates greater than 100 1/s). In addition to the experimental tests, constitutive models which accurately describe the observed strain rate dependency will developed. The goal is to develop structural constitutive models which take into account the underlying tissue morphology.
