To describe the structural and mechanical properties 
of actual deformed crystalline specimens with defects (thermal vacancies), 
simultaneous use is made of the method of correlative functions of 
the particle and vacancy distribution over the volume and the method 
of thermodynamic functionals, which implies solution of the corresponding 
variational problem in the final stage of statistical investigations. 
For the first time the tensor of microscopic deformation of the lattice 
is introduced in governing equations of statistical physics as internal 
field parameters of the system. As a result, prerequisites for a statistical 
solution of problems of elasticity theory with simultaneous description 
of the structure and mechanical characteristics of the elastic properties 
of the specimens are created.
