CHE SIGNIFICA NEUTRAL AXIS IN INGLESE
Asse neutrale
L'asse neutro è un asse nella sezione trasversale di un fascio o albero lungo il quale non esistono sollecitazioni longitudinali o ceppi. Se la sezione è simmetrica, isotropica e non è curva prima di una curva, allora l'asse neutro è al centroide geometrico. Tutte le fibre su un lato dell'asse neutro sono in stato di tensione, mentre quelle sul lato opposto sono in compressione Poiché il fascio è in fase di uniforme piegatura, un piano sul fascio rimane piano. Quello è: dove è il ceppo di taglio ed è lo sforzo di taglio C'è un ceppo di compressione nella parte superiore del fascio e un tensore di trazione nella parte inferiore del fascio. Pertanto dal teorema di valore intermedio, deve esistere un certo punto tra la parte superiore e quella inferiore che non ha alcun ceppo, in quanto il ceppo in un fascio è una funzione continua. Lasciate L la lunghezza originale del fascio ε è il ceppo in funzione della coordinata sulla faccia del fascio. Σ è lo stress in funzione della coordinata sulla faccia del fascio. Ρ è il raggio di curvatura del fascio sul suo asse neutro.
definizione di neutral axis nel dizionario inglese
La definizione dell'asse neutro nel dizionario è la linea o il piano attraverso la sezione di una trave o piastra che non subisce un'estensione o compressione quando il raggio o la piastra si piega.
