This research is concerned with the development of comprehensive injury criteria and injury-predicting finite element (FE) models, with a focus on the lower leg. Injury criteria are used by a variety of industries (e.g., automotive, defence) to evaluate protective systems, but have historically been oversimplified. Furthermore, computer models are commonly used to evaluate fracture risk, but little work has been done to ensure that bone is properly modeled. Lower leg injuries are frequent in accidents and can have significant long-term effects on quality of life. As such, there is a need for improved injury criteria and enhanced numerical models to better understand these injuries and assess the potential of novel protective technologies.

本研究关注的是全面的损伤标准和损伤预测有限元（FE）模型的发展，重点是小腿。各种行业都使用伤害标准（例如，汽车，国防）来评估保护系统，但在历史上被过于简化。此外，计算机模型通常用于评估骨折风险，但几乎没有做任何工作来确保骨骼正确建模。小腿受伤是常见的事故，并可能对生活质量产生重大的长期影响。因此，需要改进伤害标准和增强数值模型，以更好地了解这些伤害并评估新型保护技术的潜力。
