... strength pre/post-failure damage residual stretches aging layers quadrants The physiologic demands upon the aorta extend beyond that of a blood conduit. The aorta modulates cardiovascular homeostasis through the buffering of the pulsatile output of the heart and its translation into a steady...

... determinants of aortic mechanical properties which are associated with the development of an aneurysm. This study is designed to quantify the association of tissue ultimate strength and extensibility with the structural percentage of different components, in particular, GAG, and local fiber orientation...

... for separation of the nerve ends from 5 mm to 3 cm. Repairs must not only serve acutely to provide apposition of nerve ends but must enable the healing of the nerve. Using biological conduit can place suture at the ends of the conduit while fibrin glue alone eliminates suture but with limited strength...

...Janardhan Yerramshetty; Do-Gyoon Kim; Yener N. Yeni The lack of accuracy in the prediction of vertebral fracture risk from average density measurements, all external factors being equal, may not just be because bone mineral density (BMD) is less than a perfect surrogate for bone strength but also...

...). Increasing the moment arm of the applied tensile load resulted in larger head rotations, larger moments, and significantly higher tensile ultimate strengths in the upper cervical spine. The strength of the upper cervical spine when loaded through the head center of gravity ( 2417 ± 215 N ) was greater than...

... of mixtures for fiber composites to evaluate the dependence of age-related changes in tendon tensile strength ( σ ) and stiffness ( E ) on the collagen fibril cross-sectional area fraction ( ρ ) , which is related to the fibril volume fraction. Tail tendons from C57BL6 mice from age groups 1.6 – 35.3 months...

... cortical bone was tested longitudinally at strain rates ranging between 0.14 – 29.1 s − 1 in compression and 0.08–17 s − 1 in tension. Young’s modulus generally increased, across this strain rate range, for both tension and compression. Strength and strain (at maximum load) increased slightly...

...) the effect on impact severity of age-related declines (or exercise-induced enhancements) in lower extremity strength. Compared to the case of a fall with zero energy absorption in the lower extremity joints, best-case falls (which involved 81 percent activation of ankle and hip muscles, but only 23 percent...
