In diesem Artikel erhalten Sie einen \u00dcberblick \u00fcber Elastizit\u00e4t und Materialtypen, lernen das Hooke'sche Gesetz kennen, erfahren mehr \u00fcber Spannung und Dehnung und deren Formel sowie den Young-Modul, die L\u00e4ngsspannung und -dehnung und schlie\u00dflich den Elastizit\u00e4tsmodul.<\/p>\n

ELASTIZIT\u00c4T<\/h2>\n

Elastizit\u00e4t, d. h. die F\u00e4higkeit eines Materials, seine urspr\u00fcngliche Form und Gr\u00f6\u00dfe wieder anzunehmen, nachdem es durch eine \u00e4u\u00dfere Kraft verformt wurde.<\/p>\n

Elastisches Material<\/h3>\n

Es handelt sich um Materialien, die nach Wegnahme der verformenden Kraft oder nach Verformung wieder ihre urspr\u00fcngliche Form und Gr\u00f6\u00dfe annehmen.<\/p>\n

\"Elastizit\u00e4t\"<\/span><\/p>\n

Unelastisches Material<\/h3>\n

Es handelt sich um Materialien, die nach einer Verformung nicht in ihre urspr\u00fcngliche Form und Gr\u00f6\u00dfe zur\u00fcckkehren.<\/p>\n

HOOKE'S GESETZ<\/strong><\/p>\n

Sie besagt, dass, sofern die elastische Einheit eines elastischen Materials nicht \u00fcberschritten wird, die Ausdehnung \"e\" des Materials direkt proportional zur Last oder zur aufgebrachten Kraft \"f\" ist.<\/p>\n

Formel: F= -KE<\/p>\n

Zur Ermittlung der Federkonstante: K = F \u00f7 L\u00e4ngen\u00e4nderung.<\/p>\n

\u00a0STRESS<\/h3>\n

Sie ist das Verh\u00e4ltnis der aufgebrachten Kraft \"F\" zur Fl\u00e4che \"A\", auf die sie wirkt.<\/p>\n

Spannung = Kraft \u00f7 Fl\u00e4che<\/p>\n

Die Einheit f\u00fcr die Spannung ist \"Pa\".<\/p>\n

STRAIN<\/h3>\n

Es handelt sich um die relative \u00c4nderung der Abmessungen oder der Form eines K\u00f6rpers infolge einer angelegten Spannung.<\/p>\n

Dehnung = \u00c4nderung der L\u00e4nge \u00f7 urspr\u00fcngliche L\u00e4nge.<\/p>\n

L\u00c4NGSSPANNUNG UND -DEHNUNG<\/h3>\n

Bei Dr\u00e4hten, St\u00e4ben und Stangen gibt es eine L\u00e4ngsspannung, die eine L\u00e4ngen\u00e4nderung pro L\u00e4ngeneinheit bewirkt.<\/p>\n

\"Elastizit\u00e4t\"<\/span><\/p>\n

ELASTISCHE GRENZE<\/h3>\n

Sie ist die maximale Belastung, der ein K\u00f6rper ausgesetzt werden kann, ohne dass er sich dauerhaft verformt.<\/p>\n

NB: Wenn die Spannung die Bruchfestigkeit \u00fcbersteigt, bricht das Material.<\/p>\n

ELASTIZIT\u00c4TSMODUL<\/h3>\n

Vorausgesetzt, die Elastizit\u00e4tsgrenze wird nicht \u00fcberschritten und die elastische Verformung (Dehnung) ist direkt proportional zur Gr\u00f6\u00dfe der aufgebrachten Kraft pro Fl\u00e4cheneinheit.<\/p>\n

Formel = Spannung \u00f7 Dehnung.<\/p>\n

JUNGER MODULUS<\/h3>\n

Bei Materialien, deren L\u00e4nge viel gr\u00f6\u00dfer ist als die Breite oder Dicke, geht es um den L\u00e4ngselastizit\u00e4tsmodul.<\/p>\n

Y= Spannung \u00f7 Dehnung = F\/A \u00f7 L\u00e4ngen\u00e4nderung geteilt durch<\/strong> die urspr\u00fcngliche L\u00e4nge.<\/p>","protected":false},"excerpt":{"rendered":"
