| Description | Current state and historical evolution of theoretical strength calculations is presented as a brief overview completed by a database of selected theoretical and experimental results. Principles of a sophisticated analysis of mechanical stability of crystals are elucidated by means of a schematic example. Stability conditions and Jacobian matrixes are presented for selected crystalline symme-tries and deformation paths. The importance of this analysis for understanding micromechanics of fracture is shown on the background of the influence of crystal defects. Differences between theo-retical and experimental TS values are discussed and some challenging tasks are outlined for the near future. |
