...Quang Dat Tran; Sandilya Kambampati; H. Alicia Kim; Gang-Won Jang A new three-dimensional structural optimization is presented based on the level set method to obtain favorable designs for wire-fed metal additive manufacturing with uniform wall thickness. By exploiting the signed distance nature...

... the multi-material level-set method proposed by Wang et al. [ 26 ]. Similar to the single-material representation in Eq. (7) , the multiphase structural boundary ∂Ω is defined as a hypersurface of the first level-set function (i.e., ϕ ( 1 ) ( x ) = 0 ). The respective material phases...

...Hao Deng; Albert C. To This paper proposes a new parametric level set method for topology optimization based on deep neural network (DNN). In this method, the fully connected DNN is incorporated into the conventional level set methods to construct an effective approach for structural topology...

... propose a level-set method for designing monolithic compliant mechanisms made of multiple materials as an optimization of continuum heterogeneous structures. Central to the method is a multiphase level-set model that precisely specifies the distinct material regions and their sharp interfaces as well...
