Diese Arbeit befasst sich mit den Fragen, welche Bedeutung musikorientierte Jugendkulturen in der Jugendphase einnehmen und in welchem Verhältnis diese zur Kulturellen Bildung in der Offenen Kinder- und Jugendarbeit stehen. Dabei wird zu Anfang auf die Besonderheiten der Jugendphase als sozial-kulturelles Konstrukt eingegangen. Auf psychologischen und soziologischen Grundlagen werden die Bedeutungen und identitätsstiftenden Funktionen von Jugendkulturen in Verbindung mit Musik ausführlich herausgearbeitet. Die Sozialisations- und Selbstbildungsprozesse in jugendkulturellen Szenen werden mit der Kulturellen Bildung in Verbindung gebracht. Der Schwerpunkt liegt dabei auf der Kulturellen Bildung in der Offenen Kinder- und Jugendarbeit.

In this chapter, to investigate the tensile behavior of CNTs, finite element models of single-walled carbon nanotubes (SWCNTs) in perfect and doped modes for common types of carbon nanotube (CNT) configuration, i.e., the armchair, zigzag, and chiral models, were generated using a commercial finite element software (MSC Marc). To create the computational models, nodes were placed at the locations of carbon atoms and the bonds between them were modeled using three-dimensional elastic generalized beam elements. Doped models were simulated by three different heteroatoms including silicon, nitrogen, and boron separately with the doping concentration ranging from 0 to 5%. Young’s moduli of all models were obtained and compared with the perfect structures. The results indicated that Young’s modulus of chiral SWCNTs is larger than the moduli of the armchair and zigzag SWCNTs in all models and incorporating the silicon and boron atoms into CNT led to a linear reduction in Young’s modulus which was most significant for silicon and less noticeable for boron. Regarding nitrogen doping, a different trend was observed that was a negligible and less conspicuous increment in the value of Young’s modulus by increasing the percentage of doping. Besides, this behavior was the same for all armchair, zigzag, and chiral configurations with the same dopant atom. The investigations also revealed that the structural irregularity and ripples, which are induced by dopant atoms, are a key factor which influences the tensile behavior of CNTs. Our results for Young’s modulus of doped CNTs are in good agreement with recent investigations.
