This special issue of the International Journal of Multiscale Computational Engineering (IJMCE) comprises seven papers and aims to present recent advances and emerging cros s-disciplinary approaches in the broad field of uncertainty modeling and propagation in engineering mechanics w th a focus on multiscale techniques. The papers include developments at both levels of fundament al research and engineering applications of stochastic mechanics and dynamics. They are arranged in alphabetical o rder based on the name of the first author, and a concerted effort was made to achieve broad thematic perspective and ge ographic representation. Hopefully, this issue will aid toward an increasing interest and expansion of the cross-di sciplinary fields of stochastic and multiscale mechanics. The guest editors gratefully acknowledge the invitation by Prof. Jacob Fish, Editor-in-Chief of the IJMCE, to organize this special issue as well as his help and support du ring the reviewing process of the submitted papers. Further, the guest editors appreciate the effort made by the aut hors o contribute research work of high academic merit, as well as the reviewers who significantly enhanced the quality of he final manuscripts with their constructive comments.
