This involves simulation of the process using Abaqus Finite Element software as well as the development of a design methodology concerning topology and shape optimization utilizing SIMULIA Tosca. A benchmarking AM simulation is performed first to provide validation and general guidelines needed to properly implement a low-resolution AM simulation in Abaqus. The structural optimization is started by volume minimization topology optimization. Solid isotropic material with penalization fails to achieve convergence with frequency response constraints, while mass interpolation material penalization converges to a well-connected design. The design interpretation with polyNURBs results in a single component with a weight reduction of 2.29% compared to current two component assemblies. Further implementation of shape optimization to address stress design requirements allows achieving stress homogeneity and a lower weight, resulting in a 5.12% weight reduction. The AM simulation process is applied to a scaled version of the final design to both assess the printability of the part itself as well as implementation of key tools to define the AM simulation. Maximum distortion of the part appears at expected regions with an overhanging material.<\/jats:p>","DOI":"10.2351\/7.0000919","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T10:05:27Z","timestamp":1682676327000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Combination of topology and shape optimization with finite element modeling in the case of an aerospace component produced by laser based additive manufacturing"],"prefix":"10.2351","volume":"35","author":[{"given":"R.
