The aim of this study is to analyze the impact of altered geometries on
structural strength using static structural analysis. The tensile test specimens were
created using solid state modelling in Autodesk Inventor Software and analysed with
Siemens NX Software. Topology optimization was done in Autodesk Fusion 360.
Certain amounts of incavation was applied. This is a significant improvement for
weight-saving and complete design. After optimization, obtained data from first design
were recorded and compared. Incavation parts were removed following topology
optimization and then second design was created. Following the analysis of the second
design, it was decided that a new design was needed. As a consequence, the third
design was created. The analysis results of these three designs were compared with
each other. As a result of the comparison, it was observed that the second design was
34.28% lighter than the original specimen. However, in the second design, regions
with high stress values were existed. Therefore, the third design was created. The third
design is 21.43% lighter than the original specimen, and the regions with high stress
value have disappeared compared to the second design. Thus, the aim is achieved in
terms of material savings.
