As is evident, with the rise of technology, the design requirements for systems increase. Now there is the possibility of producing products with a better design to optimally serve their purpose. Optimal design can be achieved by choosing the appropriate material structure, as well as the appropriate mass distribution. In particular, the choice of basic structure is an important factor for the properties of a product. Having the most appropriate choice can increase the performance of shock absorption in structural structures (eg beam or slab). This is how the oscillations, which were caused by external causes such as vibrations, are suppressed.Also, it is crucial beyond the choice of the structure to do local optimization of the body. With the necessary study of the distribution of the forces exerted on the structural materials, we can divide the body into discrete points and investigate what deformations are exerted on them. So we have the ability to reinforce points subject to high stresses as well as remove material from where it is unnecessary. This results in a lighter construction, with a faster production rate, using less raw material.In this thesis, these possibilities will be studied. The benefits of using incremental microstructures as well as their various applications will be analyzed. They will then be modeled in 2D and 3D space using the Inventor program to understand the structure of the growth patches. Next, topological optimization of the blocks will be applied to adjust the mass distribution through the nTopology program. Finally, the structure we studied and processed will be added to perform static analysis on a beam, applying a commercial finite element program.After the stages of processing the structures are completed, we will draw a conclusion for the improvement of the ways of production of building materials. The aim of this work is to understand the effect of the stresses as well as their inclusion in the design, so as to produce a structure with enhanced properties.
