The understanding of the mechanical properties of bone is important to the understanding of bone repair. Previous studies have focused on macroscopic failure of bone material but have failed to provide evidence of strain evolution during mechanical testing. In this present study, we performed compression tests on lamb femurs to understand the failure mechanisms and the real time strain evolutio...

Recent findings suggest that vertebral osteophytes increase the resistance of the spine to compression. However, the role of vertebral osteophytes on the biomechanical response of the spine under fast dynamic compression, up to failure, is unclear. Seventeen human spine specimens composed of three vertebrae (from T5-T7 to T11-L1) and their surrounding soft tissues were harvested from nine cadav...

Y. Hu*, N.K. Kar andS.R. Nutt Gill Composites Center, Department of Chemical Engineering and Materials Science, University of Southern California, Los Angeles, California Abstract: The mechanical response of unidirectional composites subject to uniaxial transverse compressive loads was measured and analyzed by finite element simulation. Consistency in failure plane orientation was observed when...

Among all abdominal organs, the liver is one of the most frequently injured, because of its important size, weight and critical location. In car crash situations, liver injuries seem to be obtained by dynamic compression during the brutal body deceleration [2]. Some authors have described this global dynamical behaviour in compression [3-5] but not really analysed damage and failure occurrence ...

Diametral compression tests were performed on pultruded composite rods comprised of unidirectional glass or carbon fibers in a common matrix. During compression tests, acoustic emission (AE) activity was recorded and images were acquired from the sample for analysis by digital image correlation (DIC). In both composite systems, localized tensile strain developed in the transverse plane under th...

Geometric and material nonlinear behavior of slender webs in I-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. Interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. In addition, the effects of flange and web slenderness rati...
