✦ Synopsis

me fracture toughness of three Sic-materials was determined using specimens with straight-through notches and Chevron notches as well as specimens with Knoop-indentation cracks. The different procedures and results are compared and special effects such as crack-healing and crack surface interactions are discussed.

RiBrahigkeitsrnessungen an Siliziurnkarbid

An drei verschiedenen Sic-Materialien wurden RiRzahigkeitsmessungen an Biegeproben mit durchgehender Sagekerbe mit Chevron-Kerbe sowie mit Knoop-Rissen durchgefuhrt. Die unterschiedlichen Prufmethoden und die damit erhaltenen Resultate werden verglichen und spezielle Effekte wie das RiRausheilen und die Wechselwirkung der RiBflachen diskutiert.
