In the article, using the example of numerical modeling of three-point bending, an approach is proposed for optimizing the internal structure of a product, based on a preliminary calculated stress-strain state, stress-strain state (SSS) of a solid, in an elastic isotropic formulation. The internal structure is formed on the basis of the obtained isosurfaces of equivalent stresses, which form the internal load-bearing elements that ensure the strength of the structure, and transverse load-bearing elements that provide the specified stiffness, built on the basis of the Pareto law. Numerical modeling in ANSYS Workbench obtained data for an optimized sample, established the operability of the described method for the problem of three-point bending. Comparison of the results of numerical simulation, optimized and monolithic samples is given. [ABSTRACT FROM AUTHOR] |
