The main idea of energy-based hypothesis of material effort proposed by Burzynski is
briefly presented and the resulting failure criteria are discussed. Some examples, based on the
own studies, which depict applications of these criteria are discussed and visualizations of limit
surfaces in the space of principal stresses are presented.
Keywords: Burzynski yield condition, yield surface, strength differential effect, energy-based yield criteria
