The contribution is focused on characterization of methods enabling to apply small/subsized specimens for fracture resistance characterization. The applied methods are divided into transition region and upper shelf region. The approaches used in the upper shelf region represent at the same time methods applicable for ductile materials without transition. Relating to subsized samples two basic approaches are applicable: (i) miniaturized samples based on common standard ones and (ii) specific specimens/methods, e.g. small punch test etc. The results described in the paper belong to the first group. For interpretation of data generated under low constraint conditions toughness scaling models and master curve approached are commented. In ductile region, either the sample used generate valid toughness characteristics, or, if not, there is no way how to correct measured data except damage quantification through micromechanical models.

Abstract: State Nonconceptualism is the view that perceptual states (not perceptual content) are different in kind from cognitive states (not cognitive content), insofar as a subject could be in perceptual states even if she lacked the concepts necessary to describe those states. Although this position has recently met serious criticism, this piece aims to argue on its behalf. A point I specifically want to highlight is that, thanks to State Nonconceptualism, it is possible to characterize perceptual experiences as nonconceptual or concept-independent without relying on the notion of perceptual content - a feature I term here the content independence of State Nonconceptualism. I think one should welcome this result: for, although a nonconceptualist characterization of perceptual experience is quite plausible, nonrepresentationalist approaches to perception have persuasively challenged the thought that perceptual experiences have representational content. This brief piece is divided into three parts: (i) I introduce two versions of Perceptual Nonconceptualism, namely, Content and State Nonconceptualism; (ii) I go on to stress State Nonconceptualism’s content independence; and (iii), I briefly address three prominent objections against the state nonconceptualist.
