Description
FEM (finite element method) today is used in linear-elastic as well as elastoplastic fracture mechanics. The important parameter is the factor of critical stress intensity. Elastoplastic stress and dislocation fields may be calculated in two and three dimensions. It is also possible to look for criteria to be transferred. The local conditions directly in front of the tip of the crack are of importance. The problem of the long computing times that sometimes is still existing today will become less important if new computer generations are introduced. (orig.)
Abstract (German)
Die FEM (Finite Element Method) verwendet man heute sowohl in der linearelastischen als auch in der elastoplastischen Bruchmechanik. Die wesentliche Groesse ist der kritische Spannungsintensitaetsfaktor. Elastoplastische Spannungs- und Verschiebungsfelder koennen zwei- und dreidimensional berechnet werden. Es besteht gleichfalls die Moeglichkeit, nach uebertragbaren Kriterien zu suchen. Von Bedeutung sind die lokalen Verhaeltnisse unmittelbar vor der Rissspitze. Das heute noch teilweise vorhandene Problem der grossen Rechenzeiten wird beim Einfuehren von neuen Rechnergeneration an Bedeutung verlieren. (orig.)Additional details
