Tiivistelmä

A continuum approach is proposed for modelling multiaxial high-cycle fatigue
of solids which exhibit transversely isotropic fatigue properties. The approach is
an extension of the original isotropic model proposed by Ottosen, Stenstr¨om and
Ristinmaa in 2008, which model is based on the concept of a moving endurance
surface in the stress space and on an evolving damage variable. The theory is
formulated in a rate form within continuum mechanics framework without the
need to measure damage changes per loading cycles. Capability of the approach
is illustrated by several examples with different uni- and multiaxial loading
histories.
