Biaxial Mechanical Evaluation of Uterosacral and Cardinal Ligaments
… United States annually. Despite their important mechanical function, little is known about the elastic and viscoelastic properties of the USL and CL due to ethical concerns with in vivo testing of human tissues and the lack of accepted animal models. The goal of this first study is to help …

Mechanical Evaluation of Mandibular Defects Restored with rhBMP-2: A Finite Element Model
… to autogenous bone grafts. Understanding the biomechanical properties of rhBMP-2 restored mandibular defects would provide useful knowledge in the future success of orthopedic and dental treatment in patients who have had restoration of mandibular defects with rhBMP-2. The aim of the study was to …

A chemical and mechanical evaluation of interfacial fracture in dicyandiamide cured epoxy/steel adhesive systems
… concentration, and the cure temperature. Bulk mechanical measurements were conducted to provide background information for comparison with the fracture data, and surface analyses were carried out on the neat adhesives and failed fracture specimens to provide insight into the locus and causes of …

Mechanical evaluation of a modified prosthetic laryngoplasty using a toggle technique for the equine arytenoid cartilage
… objectives of this study were to compare the biomechanical properties of the standard technique to the modified laryngoplasty technique in both monotonic and cyclic loading. Larynges from 41 horses were collected following euthanasia and used for mechanical testing. Laryngoplasty constructs were …

Evaluation of Graft Pretension Effects in Anterior Cruciate Ligament Reconstruction: A Series of In Vitro and In Vivo Experiments
… for biped and quadruped stances. Third, the mechanical characteristics of porcine patellar tendon (PT) were investigated by uniaxial tensile testing at two strain rates. Patella-PT-tibia complexes from freshly sacrificed skeletally immature and mature animals were loaded to failure at …
