(2018), "Development and validation of a new finite element human head model: Yet another head model (YEAHM)", Engineering Computations, Vol. We will find out whether or not the model is good enough in Phase 4. Citationįernandes, F.A.O., Tchepel, D., Alves de Sousa, R.J. to control the modeling error, we may have to choose a better mathematical model. then you can give whatever time period you desire and any Mass scaling or velocity you want as long as you. it means you can have a stable solution like standard solver if and only if the above ratio is dealt. The authors also acknowledge Dr Alfredo Calheiros from the Hospital Geral de Santo Antonio, Porto, for providing the medical images and Professors Paula Martins, Silvia Francesco (University of Aveiro) and Teresa Magalhães (University of Porto) for the fruitful discussions. To have a quasi static problem using Explicit solver, you need to pay attention to the Kinetic to internal energies ratio which should not be more than 10. The authors are grateful to the Portuguese Foundation for Science and Technology (FCT), which financially supported this work, through the scholarship SFRH/BD/91292/2012. It gives good displacement solutions for linear elastic materials and provides increased resistance to hourglassing for nonlinear materials.
As this model is validated, it can be now used in accident reconstruction and injury evaluation and even as a design tool for protective head gear. The enhanced hourglass control option available in ABAQUS uses stiffness coefficients based on the enhanced assumed strain method.
