A pregnant woman model to study injury mechanisms in car crashes
Based on statistical analysis it has been estimated that 3 to 7% of pregnant women experience trauma, 2 third of those trauma are caused by car accidents. According to one epidemiologic study, the frequency of foetal losses could ...

The use of different CSF representations in a numerical head model and their effect on the results of FE head impact analyses
To gain better insight in the mechanopathogenesis of brain and skull lesions and to improve the design of protective devices like helmets, finite element (FE) head models are used. Current FE head models have a detailed geometrical ...

Development of a thorax finite element model for thoracic injury assessment
Kinetic energy non-lethal weapons (KE-NLW) are now widely used by law enforcement, by military forces, by the police in situations where the use of lethal arms is not required or suitable. Unfortunately, their effects are still not ...

Implementation of a Strain Rate Dependent Human Bone Model
Strain rate dependency of mechanical properties of cortical bone has been well demonstrated in literature studies. Nevertheless, the majority of these studies have been done on nonhuman bone and at lower magnitudes of strain rates. ...

MPP Execution of Implicit Mechanics with 10M or More Elements
LS-DYNA models for Implicit Mechanics are getting larger and more complex. We are continually seeing models where the linear algebra problems in Implicit Mechanics have 3 to 5 million elements and know of at least one that is nearly ...
