This Festschrift is dedicated to Professor Dr.-Ing. habil. Peter Wriggers on the occasion of his  60th birthday. It contains contributions from friends and collaborators as well as current and
former PhD students from almost all continents. As a very diverse group of people, the  authors cover a wide range of topics from fundamental research to industrial applications: contact mechanics, finite element technology, micromechanics, multiscale approaches,
particle methods, isogeometric analysis, stochastic methods and further research interests. In  summary, the volume presents an overview of the international state of the art in computational mechanics, both in academia and industry.
