摘要: The questions investigated in this article are related to an important class of problems optimal structural design concerning the shape optimization quasibrittle elastic bodies with cracks. taken into consideration consist finding boundary a body loaded by cyclic quasistatical forces such way that cost functional (volume body) reaches minimum, while satisfying some prescribed bounds on longevity (i.e., number cycles before destruction). These characterized incomplete information initial crack size and location. In context, presents possible formulations problems, based probabilistic approaches, examples analytical solutions.
