Abstracts:

In the paper the problem of calculating of the optimal loading pressure during material deformation under creep is considered. The solution of the boundary-value problem is constructed within the frameworks of the model of large elastic-creep deformations. The obtained numerical solution is used to find the optimal loading process necessary to achieve a given size of a single microdefect. The search for the optimal solution is carried out on the set of 5–order polynomials by a brute-force search. The resulting solution is analyzed graphically and compared with previously obtained results.
