“…These approaches usually concentrated on a single crack behavior and did not consider the effects of a group of cracks. Researches [5][6][7][8] indicated that the material fatigue damage process is actually caused by all cracks, and these cracks' behavior can show a strong collective behavior and random statistical complexity. Therefore, it is necessary to put forward a new approach which can allow for and implement collective evolution of short fatigue cracks.…”

“…A análise fractográfica por MEV revelou a real geometria da trinca e da fragmentação. A metodologia usada na análise fractal por impacto mecânico trouxe como resultado a revelação de parâmetros diferentes da medida de resistência à flexão em três pontos [18]. Estas duas análises são obviamente diferentes, contudo, foi possível por meio da análise fractal da fragmentação entender um pouco mais dos mecanismos envolvidos no processo de fragmentação, o que não foi possível com um simples ensaio de flexão.…”

“…Parametry fraktalne opisują zarówno wysokość nierówności, jak i ich kształt. metody fraktalne były stosowane do: scharakteryzowania chropowatości powłok z częściowo stabilizowanego tlenku cyrkonu natapianych metodą laserową [22], charakteryzowania porowatości powłok nakładanych metodą hybrydową płomieniowo-laserową [23], badania związku pomię-dzy odpornością na pękanie i strukturą geometryczną powierzchni przełomu [24], związku pomiędzy odpornością na pękanie kompozytów ceramicznych i drogą rozwoju pęknięcia [25]. Stwierdzono również związek pomiędzy przyczepnością i parametrami fraktalnymi opisującymi powierzchnię podłoża [26,27].…”
