Resultant Loads And Elastic Modulus Calibration Of Long Bone Cross Sections.
Published 1981 · Engineering, Medicine
Abstract A method of calibrating a long bone cross-section for the resultant axial force and bending moments is presented. At least three single gages must be bonded at circumferential locations at the section of interest. In the laboratory, strains are recorded when known anterior-posterior and lateral-medial bending moments are applied. Strains are also recorded when a known axial force (of unknown eccentricity) is applied. From these measurements one can calculate the resultant loads acting at the section whenever the three simultaneously recorded strain values are known. In addition, the section axial stiffness and effective axial elastic modulus of the section can be determined. This calibration method is especially pertinent in the analysis of in vivo bone strains which have been previously recorded.
