Original abstract

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 symmetries 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 theoretical and experimental TS values are discussed and some challenging tasks are outlined for the near future.

Současný stav a historický vývoj výpočtů teoretické pevnosti je uveden ve stručném přehledu, doplněném databází vybraných teoretických a experimentálních výsledků. Principy sofistikované analýzy mechanické stability krystalů jsou vysvětleny na příkladech. Jsou uvedeny podmínky stability a Jacobiho matice pro vybrané krystalové symmetrie a deformační dráhy. Je ukázán význam této analýzy pro porozumnění mikromechanice lomu na pozadí vlivu poruch krystalů. Rozdíly mezi teoretickými a experimentálními hodnotami TP jsou diskutovány a jsou tak naznačeny úkoly pro další období.
