The homogenization of the stresses on a components surface
often indirectly leads to a reduction of the maximum damage in these
areas. In SIMULIA Tosca Structure,
a durability analysis can be included in the optimization loop. The
direct use of damage results for the homogenization strategy leads to
a minimization of the maximum damage in the critical areas. In SIMULIA Tosca Structure,
the damage values must be provided as equivalent stress values. The
coupling of a durability analysis enables the consideration of the load-time
histories. The notions fatigue, durability, and life analysis will all
be used in the following as the same thing.
