Henryk Petryk – författare

This commemorative volume celebrates 50 years of Henryk Petryk's scientific career and his distinguished contributions to the theory of plastic instability, a critical area in materials science and mechanical engineering. His thirteen selected individual works are preceded by a new unifying introduction, which creates a coherent monograph. Its core consists of the first three extensive chapters—originally published in the prestigious Springer series CISM Courses and Lectures—and the most recent final chapter. Curated to showcase the evolution and enduring relevance of his pioneering research, this collection offers both a historical perspective and authoritative insights into one of the field’s most challenging topics.

This book collects recent theoretical developments in the area of material instability in elastic and plastic solids along with related analytical and numerical methods and applications. The existing different approaches to instability phenomena in metal single crystals, polycristals and in geomaterials are presented with the emphasis laid on mutual relations and on unifying concepts, including elliptictly loss and the energy criterion. Quasi-static bifurcation, initiation of single or multiple shear bands and post-critical strain localization are examined along with dynamic phenomena as wave propagation, moving shocks, internal snap-through and instability of flutter type. This gives an overview of a variety of material instability problems, methods and applications.
