Analysis of crack singularities in an aging elastic material. (English) Zbl 1106.74028
Summary: We consider a quasistatic system involving a Volterra kernel modelling an hereditarily-elastic aging body. We are concerned with the behavior of displacement and stress fields in the neighborhood of cracks. We investigate the case of a straight crack in a two-dimensional domain with a possibly anisotropic material law. We study the asymptotics of the time-dependent solution near the crack tips. We prove that, depending on the regularity of material law and Volterra kernel, these asymptotics contain singular functions which are simple homogeneous functions of degree $$\frac12$$ or have a more complicated dependence on the distance $$r$$ from the crack tip. In the latter situation, we observe a novel behavior of singular functions, incompatible with usual fracture criteria which involve super-polynomial functions of $$\ln r$$ growing in time.
