Numerical Analysis of the Lamb Metacarpal Bone: Approximation of Bending Tests

In the development of new strategies for fracture fixation, new methods have to be tested biomechanically under in vitro conditions before clinical trials can be performed. Several studies, including tensile, compressive, and bending tests for fresh whole bone specimens, offer the possibility to understand animal bones mechanical behavior. Therefore, in the present study three point bending tests were applied on the lamb metacarpal bones at different speeds and determine the mechanical properties of bone. For the experiments 12 specimens were obtained from 1 year old Ankara curly lambs and three point bending tests were conducted using three different bending speeds to assess and compare bone fracture properties. From the test results strains, deformations and stresses were calculated for three different bending compression speeds. Finite Element Analysis results were compared to the test results. Because of the use fresh bone specimens of an animal part are used like in vivo tests in biomechanical studies, investigating failure loads of the metacarpus by bending tests and numerical analysis are guiding for clinical operations and computer simulations.
