Structural Characterization of Human Rib Cage Behavior under Dynamic Loading

Construction and evaluation of thoracic injury risk curves for a finite element human body model in frontal car crashes

“…Additional mechanisms, i.e. rotation of the ribs and bending out of the plane were found by Vezin and Berthet (2009) while dynamically loading eviscerated rib cages. These additional mechanisms were also identified by Mendoza-Vazquez et al (2013) in simulations of impactor and sled tests with the modified THUMS.…”

Geometrical personalisation of human FE model using palpable markers on volunteers

“…Its ability to generate models of the rib cage from bony landmarks has been demonstrated by Vezin and Berthet (November 2009), but also in previous studies Serre et al July 2006), which considered external landmarks of HUMOS2 50th percentile male FE model to create the small female and the large male models.…”

“…The THUMS personalisation was carried out using a method based on radial basis function (RBF; Buhmann 2003) which is widely spread to personalise FE meshes using control points (Besnault et al 1998;Bertrand et al 2006;Serre et al July 2006;Vezin and Berthet November 2009). Its ability to generate models of the rib cage from bony landmarks has been demonstrated by Vezin and Berthet (November 2009), but also in previous studies Serre et al July 2006), which considered external landmarks of HUMOS2 50th percentile male FE model to create the small female and the large male models.…”

“…This trend may be linked to several concomitant changes in the properties of biological tissues (Zhou et al 1996), costo-vertebral, costo-chondral joint stiffnesses and joint limits, but also to different thorax morphotypes (Gayzik et al 2008;Vezin and Berthet November 2009). This study aims at quantifying the influence of main geometrical parameters on thorax mechanical response. To achieve this goal, finite element (FE) simulations using the total human model for safety (THUMS) are carried out by modifying only THUMS anthropometry and thorax geometry while keeping constant the other factors.…”

Thoracic response targets for a computational model: A hierarchical approach to assess the biofidelity of a 50th-percentile occupant male finite element model

“…the thorax deforms under dynamic loading applied by improved restraint systems to vehicle occupants is an active area of research. Finite element (FE) models of the human thorax or the entire body have been developed to investigate the structural response of the thorax in vehicle crashes and to establish its injury tolerance (Robin, 2001;Iwamoto et al, 2002;Ruan et al, 2003;Kimpara et al, 2005;Zhao and Narwani, 2005;Song et al, 2009;Ito et al, 2009;Vezin and Berthet, 2009). The biofidelity of the majority of the existing thorax models have been typically evaluated against frontal pendulum impacts (Kroell and Schneider, 1971) and lateral impacts (Lau and Viano, 1988;Shaw et al, 2006) by comparing the global responses of the FE model to the experimental responses of various post-mortem human surrogates (PMHS) at a given impact velocity.…”
