Marta Carvalho


• Fundamental concepts about numerical simulation applied to the study of passive passenger safety.
• Potentials and limitations of the use of commercial codes, encouraging their rational and appropriate use with regard to the representation of real systems and their components.

Requirements on previous knowledge



• Presentation and definition of concepts and objectives using LS-Dyna; Typical train interior configurations.
• Workshop: introduction to LS-PrePost (2 classes of basic examples in which pre- and post-processing of models in LS-Dyna is carried out).
• Impact biomechanics (2 classes): injury mechanisms, injury criteria, standards and regulations. Anthropomorphic testing devices; Applications in LS-DYNA.
