We ask readers to excuse us for temporary inconvenience. The ENERGYDURABILITY website will be reconstructed by the author taking into account new theoretical and practical results accumulated over a long period of time.

New version of the site

A new analytical tool, a new method for testing the physical and mechanical parameters of a material, a universal physical characteristic - the volume derivative of the specific energy of a deformed solid, also called the generalized specific power of the process of changing the shape during indentation, or briefly - the physical hardness of the material - is used in the physical theory of strength and hardness. This is a new universal physical and mechanical characteristic of the state of a material during its deformation and destruction, analytically it is unambiguously related to the usual empirical standard parameters of the hardness number, tensile strength, brittleness, etc.

My independent work on the theory, as an independent researcher, is not funded by any organizations. You can help me speed up the work process if you order the specific theoretical material you need (article, abstract, lecture, etc.). To do this, you need to send an order to the author of the theory and the site Nikolay Shtyrov by E-mail: This email address is being protected from spambots. You need JavaScript enabled to view it. . The Order Form is attached below.

Previous theoretical results, methods, etc. published on the ENERGYDURABILITY site before 2022 require additions and corrections to many concepts, designations, definitions, etc. have changed. These works will be consistently carried out within the framework of NEWCONCEPTION - ED, but the originals are stored in the archive of the first version of the site.

Body straining and fracture in terms of the kinetic structure-and-energy failure theory.

The physical definition for molar thermal-motion energy of idealized particles of the condensed medium is used for wording the generalized structure-and-energy kinetic model of the strained body. New physical molar characteristics and physical law of the strained body structure-and-energy state are substantiated. Its proof and interpretation draw on known experimental results of the kinetic strength concept. The obtained constitutive equations and relationships allow viewing the strained body under non-stationary loading and combined stress state by the concept of elasticity theory and statistical thermodynamics of irreversible processes. Examples of new experimentally generalized and analytically estimated physical kinetic parameters and relationships for solving application tasks on strength, fatigue, etc. of different materials are given. Some problems on strength, fatigue and fracture mechanics are solved analytically and numerically by utilization of the new approach. The physical strength theory simplifies analytical methods for strength, durability and reduces the amount of material experimental parameters (limit of failure, fatigue, etc.); it is basis of new analytical investigative techniques and development of physical mechanical properties for materials. Output of the work corresponds adequately with theoretical and experimental data obtained from the independent studies and confirms the received physical regularities and relationships.
