Kristallplastizität

Plastizität von Werkstoffen

Kristallplastizität

Kristallplastizität beschreibt die irreversiblen Verformungsmechanismen in kristallinen Werkstoffen auf der Ebene von Kristallgittern und Gleitsystemen. Sie basiert auf der Bewegung von Versetzungen entlang definierter Gleitebenen und -richtungen und umfasst auch Zwillingsbildung sowie ggf. Diffusionskriechen. Kristallplastizitätsmodelle koppeln Anisotropie, Texturentwicklung und Gefügeänderungen mit lokalen Spannungs- und Dehnungsfeldern und bilden die Grundlage für skalenübergreifende, mechanische Werkstoffsimulationen.
