In dieser Arbeit werden die asymptotischen Nahfeldloesungen des stationaer wachsenden Risses systematisch untersucht. Dabei besteht die Arbeit aus drei Teilen. Im ersten Teil handelt es sich um die systematischen Untersuchungen der Rissspitzenfelder, die Rissoeffnungsprofile, das J-Integral, die Rissspitzenoeffnung CTOD und eine neue Definition von dem Rissspitzenoeffnungswinkels CTOA auf der Basis des stationaer wachsenden Risses. Der zweite Teil behandelt die Entwicklung eines Finite-Elemente-Verfahrens, das in der Lage ist, die asymptotischen Nahfeldloesungen des stationaer wachsenden Risses zu ermitteln. Im dritten Teil wird der Spannungszustand an stationaer wachsendem Riss in realen Proben durch numerische Simulationen von Experimente...
