Scherfläche S

Beitragvon Rubens am Fr 12. Dez 2014, 15:55

Hallo zusammen,

ich habe ein Verständnisproblem mit der Scherfläche eines Bauteils.
Also, es handelt sich um den Querschnitt bzw. den Flächeninhalt eines Körpers. Nur welchen ?

Beispiel mit diesem U-Profil:

http://img5.fotos-hochladen.net/uploads ... c4u98h.jpg

Welchen Flächeninhalt habe ich zu berechnen? Die der seitlichen Ansicht. (Dreieck + Rechteck) oder ist es die Grundseite (U-Profil)
Auf zwei Internetseiten zum Thema wurden Berechnungsformeln für runde Querschnitte gewählt. Wie z.B. pi+r^2 bzw. pi+(d^2)/4. Auch wenn die Rede von Blechen und nicht von Rohren, Bolzen usw. war.
Ihr merkt, ich bin etwas verwirrt. Ich freue mich über Aufklärung.

Gruß Rubens.
Rubens
