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。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得到很好的理解。我们的研究小组研究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的影响，其中最常见的是汽车事故。这个博士项目的重点是结合理论和实验工具的开发，以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载荷条件下（应变率大于100 1/s）测试蒙皮。除了实验测试，准确地描述所观察到的应变率依赖性的本构模型将开发。我们的目标是开发结构本构模型，考虑到潜在的组织形态。

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.
