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.

韧带、肌腱和皮肤等软组织具有时间和历史依赖性。尽管实验和理论生物力学取得了许多进展，但这些软生物结构的材料特性仍然没有得到很好的了解。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承受动态载荷，最常见的情况之一就是汽车事故。该博士项目的重点是开发理论和实验相结合的工具来捕获软组织的应变率依赖性行为。实验工作将涉及在动态拉伸负载条件（应变率大于 100 1/s）下测试皮肤。除了实验测试之外，还将开发准确描述观察到的应变率依赖性的本构模型。目标是开发考虑潜在组织形态的结构本构模型。
