16. Development of an Anisotropic Finite Element Head Model for Traumatic Brain Injury Prediction
Abstract : Traumatic brain injury (TBI) is a worldwide health care problem with very high associatedmorbidity and mortality rates. In particular, the diagnosis of TBI is challenging: symptomsoverlap with other pathologies and the injury is typically not visible with conventionalneuroimaging techniques. READ MORE

17. Hydro-mechanical forming of aluminium tubes : on constitutive modelling and process design
Abstract : Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. READ MORE

18. Constitutive models based on dislocation density : formulation and implementation into finite element codes
Abstract : Correct description of the material behaviour is an extra challenge in simulation of the materials processing and manufacturing processes such as metal forming. Material models must account for varying strain, strain rate and temperature, and changing microstructure. READ MORE

19. Multiphase continuum modeling of wood : A hybrid mixture theory approach
Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

20. Multiscale Constitutive Modeling of Heterogeneous Engineering Materials
Abstract : This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development.
