TY - JOUR PY - 2013// TI - Sport helmet design and virtual impact test by image-based finite element modeling JO - Conference proceedings - IEEE engineering in medicine and biology society A1 - Luo, Yunhua A1 - Liang, Zhaoyang SP - 7237 EP - 7240 VL - 2013 IS - N2 - Head injury has been a major concern in various sports, especially in contact sports such as American football and ice hockey. Helmet has been adopted as a protective device in such sports, aiming at preventing or at least alleviating head injuries. However, there exist two challenges in current helmet design and test. One is that the helmet does not fit the subject's head well; the other is that current helmet testing methods are not able to provide accurate information about intracranial pressure and stress/strain level in brain tissues during impact. To meet the challenges, an image-based finite element modeling procedure was proposed to design subject-specific helmet and to conduct virtual impact test. In the procedure, a set of medical images such as computed tomography (CT) and magnetic resonance image (MRI) of the subject's head was used to construct geometric shape of the helmet and to develop a helmet-head finite element model that can be used in the virtual impact test.
