Model Based Head Injury Criteria within Industry

Course Description To prevent injuries resulting from head impacts inside and outside the car, the next generation of head protection design will have to be based on improved model based head injury criteria including virtual or coupled experimental and virtual methods. These novel approaches will consider linear and rotational head acceleration vs time and take into account a range of head injury mechanisms. By implementing recent research tools into new design methods, it will be pos- sible in a near future, to propose protective structures and panels to be optimized against biomechanical injury criteria including the challenging aspect of mild brain injury. Course Objectives The objective of this course is to provide an overview of head trauma biomechanics and existing head injury criteria. Focus will then be on the state of the art in the domain of human head FE modeling, both its limitations and its recent achieve- ments. Special attention will be paid to real world head trauma reconstruction and the derivation of model based head injury criteria. Finally the novel head injury prediction tool SUFEHM (Strasbourg University Finite Element Head Model) will be presented, with special focus to its implemen- tation into an industrial environment It will be shown how the assessment of head injury risk is conducted in the context of an experimental crash scenario and how new protection design is evaluated in a virtual testing environment. Who should attend? This seminar is especially suited for engineers and technicians who work on experimental or numerical development of vehicle interior parts or pedestrian protection, who want to prepare the next generation of head protection design based on virtual methods.

A pre-conference seminar of

Prof. Dr. Rémy Willinger (University of Strasbourg) has been leading a research group focusing on head & neck impact biomechanics at Strasbourg University, Strasbourg, France since 1990. The research activity of this lab focuses on experimental characterization of biological tissue, head and neck FE modeling and injury mechanisms investigation via accident simulation. Development of injury criteria and protection systems modeling and optimization are also part of his skills. This group contributed to seven EU projects and conducted no less than 70 contracts with public institutions and private companies.
