“…Also the range of the interaction in a real material sample can be affected by the correlation length of any disorder (see e.g. [35]), the size of any aggregates or agglomerates in ceramics [36] or the size of a plastic or process zone in a ductile metal [37,38], for example. We find that the inverse square interaction lies in the middle of a continuously changing set of critical exponents for the roughness and avalanche size distributions.…”

The fiber bundle model is essentially an array of elements that break when sufficient load is applied on them. With a local loading mechanism, this can serve as a model for a one-dimensional interface separating the broken and unbroken parts of a solid in mode-I fracture. The interface can propagate through the system depending on the loading rate and disorder present in the failure thresholds of the fibers. In the presence of a quasi-static drive, the intermittent dynamics of the interface mimic front propagation in disordered media. Such situations appear in diverse physical systems such as mode-I crack propagation, domain wall dynamics in magnets, charge density waves, contact lines in wetting etc. We study the effect of the range of interaction, i.e. the neighborhood of the interface affected following a local perturbation, on the statistics of the intermittent dynamics of the front. There exists a crossover from local to global behavior as the range of interaction grows and a continuously varying 'universality' in the intermediate range. This means that the interaction range is a relevant parameter of any resulting physics. This is particularly relevant in view of the fact that there is a scatter in the experimental observations of the exponents, in even idealized experiments on fracture fronts, and also a possibility in changing the interaction range in real samples.

“…In the case considered, the cyclic load leads to two basic effects [5]: 1) acceleration (or even initiation) of the creep process under a given static stress a0; 2) reduction of the accumulated inelastic deformation at the moment of destruction as compared to that under purely static loading. From the analysis of papers on cyclic creep [6,[9][10][11], the following approaches can be conventionally distinguished at the phenomenological level. It is usually impossible to describe these phenomena within the framework of traditional classical approaches, or phenomenological creep [7], or fatigue under an asymmetric cycle [8].…”

A uniaxial phenomenological energetic model for description of inelastic deformation and destruction of metals under a joint action of static and cyclic loads is proposed. The amplitude value of the cyclic component of stress in experiments was less than 10% of static loading. The model proposed was carefully verified in experiments with the 1~P742 alloy for T = 650 and 750~ The numerical and experimental data are in good agreement.
