To develop a strategy for justifying highly effective technical solutions by finding rational sets of design and technological parameters of body systems "discretely hardened part - continually hardened part". 2. To develop a variable model of the stress-strain state of a representative cell of discretely and continually strengthened bodies in an extended parametric space. 3. Investigate the effect of varying design and technological parameters of discrete-continuous hardening on the stress-strain state of contacting bodies. 4. To develop recommendations on design and technological parameters of discrete-continuous strengthening of MSCP elements (on the example of engine elements for armored vehicles of the 6TD and 3TD types, tank gun barrels, diesel locomotives and diesel engines, and units for autonomous power sources for strategic facilities, etc. popup.description2 The object of research is physical and mechanical processes and states during discrete-continuous strengthening and contact interaction of elements of military and civilian vehicles. Purpose of the research is improving of technical and tactical characteristics of military and civilian vehicles to a level that meets and exceeds the world standards by analyzing the impact on the contact interaction and strength of their elements and substantiating recommendations for effective design and technological parameters of discrete-continuous hardening. Research methods are finite element method; method of variational calculus; method of additional gaps; method of computational and experimental studies. A strategy for substantiating highly efficient technical solutions by searching for rational sets of design and technological parameters of body systems "discretely strengthened part - continually strengthened part" has been developed. An improved variational model of the stress-strain state of a representative cell of discretely-continuously strengthened bodies in an extended parametric space has been developed.. The influence of variable design and technological parameters of discrete-continuous hardening on the stress-strain state of contacting bodies is investigated. Recommendations on design and technological parameters of discrete and continuous strengthening of military and civilian vehicles elements (on the example of engine elements for armored vehicles of the 6TD and 3TD types, tank gun barrels, diesel locomotives and diesel engines, and units for autonomous power supplies for strategic facilities, etc.) have been developed that ensure the world level of their technical and tactical characteristics. A study of test samples of discrete-continuous hardened bodies was carried out. Product Description popup.authors Mykola A. Tkachuk Mykola M. Tkachuk Andrii P. Marchenko Amir Н. Lal Maksym S.
