A finite element human torso model was developed from high resolution CT data. ImageSim platform (VOLMO LTD ( UK)) was used to create a detailed model consisting of Liver , Rib cage and Lungs. Model assembly and alignment was done in TSV Pre (TechnoStar Japan) . The Analysis was performed using LS-DYNA971
CT data of healthy adult male was imported into imagesim & the geometry of the components of whole model were reconstructed from CT data using imagesim. The model consists of geometrically detailed liver, rib cage and lungs.
The FE model used in this study was developed in TSV pre using STL models created in imagesim. TSV pre is a robust CAE environment and can be invoked from imagesim. Automatic volume mesher was used to generate high quality tetrahedral meshing.
Torso model was hit by rigid body with an effective mass was 489.393 g from frontal, lateral and rear directions with impact velocities 6 m/s, during the impact process only the lower part of the spine was fixed. termination time was set to 6 ms and time interval between outputs was set to 0.1 ms.
