DESCRIPTION:Michelle L. Oyen\,\nLecturer in Mechanics of Biological Materi
 als\,\nEngineering Department\, Cambridge University\n\n\nSoft Tissue Frac
 ture: Injury and Related Research\n\nTraumatic injuries to structural soft
  tissues arise in many circumstances including automobile accidents and sp
 orting events. While fracture of bone has been studied extensively\, very 
 little research has considered the biomechanics of fracture in soft tissue
 s. To motivate detailed biomechanical investigation of crack propagation i
 n soft tissues\, impact studies on bovine patellar cartilage are considere
 d.  There is a direct correlation between cell death and cartilage crackin
 g following direct impact loads.  However\, the mechanics of crack propaga
 tion in networks of fibrillar collageneous tissues presents many challenge
 s.  Methods are developed for quantifying crack propagation in soft tissue
  membrane samples.  Fracture testing results are compared for two differen
 t soft tissues with different underlying microstructures. The role of wate
 r content in cartilage fracture is examined.  The potential application of
  these new fracture mechanics techniques to the study of intervertebral di
 sc herniation\, cartilage injury and meniscal tears will be discussed.\n
