EN Purpose: Physically based understanding, associate fracture processes to local origins. Even so, in elastic-plastic solids the continuum analysis is mainly engaged with the macroscopic scale. Beside global views the current study emphasise the coupled aspects that are determined by local and material-based factors. Design/methodology/approach: Theoretical/experimental interfaces were adopted mainly cantered on interaction problems. Load interaction in static or dynamic loading and deformation/environment interactions were selected. For the load interaction cases, construction materials were investigated. A metastable stainless steel and hydrogen represented the environment interaction case. Experimentally, novel techniques have been utilized mainly on the nano scale including contact methodology and probe microscope visualization. Findings: The macroscopic background that was supplemented by local findings enabled to refine viable models in quantitative terms. Research limitations/implications: The nano mechanical approach allows additional options to be taken in terms of critical experiments or in order to improve multi-scale models. Originality/value: The nowadays contribution by small volume activities as related to complicated technological topics are highly promising. These avenues are only in early stages, with increasing incentives to advance capabilities assisting applications in nano technology.
