Özet
Mesoscale lattice structures can be used in the design of lightweight structures using additive manufacturing without significantly raising production costs. However, creating effective structures with intricate latticework is difficult. Therefore, this paper presents a new strategy for designing additively manufactured structures that can simultaneously optimize the continuum structures. A novel hybrid algorithm has been created by combining the density-based approach, shape optimization, and element removal method (D-S-ER) to achieve the desired purposes of higher strength and/or lightweight structures. Three distinct issues-the cantilever beam, the corbel structure, and the GE bracket-that were addressed by many scientists were taken into account and resolved using the method that has been developed. As seen from the tables presenting the results obtained, significant improvements in terms of strength as well as the weight of the structures can be obtained. Hence, the results of the study demonstrate the effectiveness of the proposed procedure.
