Extremal Character

One of the possible approaches to the analysis of a physical mechanism of time dependence for the resistance coefficients of materials is suggested. The material durability at the constant stress is described using the Zhurkov and Gul' equations and the durability at the alternating stress—using the Bailey criterion. The low strains lead to structuring of a material that is reflected in a reduction of the structure-sensitive coefficient in these equations. This affords 20% increase in the durability. The dependence of the resistance coefficient assumes an extremal character; the maximum is observed at the time to rupture lg tr ≈ 2 (s).

The Subject

This introduces the subject, laying out the organisation of the book and emphasising the importance of both simple underlying physical mechanisms and evolutionary variability to thermal ecology. It distinguishes physical mechanism from statistical description, and the importance of evolutionary processes in comparisons across species.
