This project will study crack propagation in articular cartilage in the underlying bone of joints using both analytical and experimental techniques. Finite element analytical models, using layers of two different materials, will be constructed to study the parameters that influence the fracture process. The experiments will be used to verify the theoretical predictions and to determine the morphology of impact-induced cracks in osteoarthritic animals. The work is expected to provide new basic information on the load bearing capability of layered soft materials. The eventual benefit will be a new understanding of fracture in joints, and in using this new knowledge to design novel impact resistant materials.

这个项目将使用分析和实验技术研究关节底层骨中关节软骨中的裂纹扩展。将建立有限元分析模型，使用两种不同的材料层来研究影响断裂过程的参数。这些实验将被用来验证理论预测，并确定骨关节炎动物撞击诱导的裂缝的形态。这项工作有望为层状软材料的承载能力提供新的基本信息。最终的好处将是对关节骨折有了新的理解，并利用这一新知识来设计新型的抗冲击材料。
