WebApr 15, 2024 · This paper presents a topology optimization algorithm to deal with elastoplastic and layer-by-layer simulation for the additive manufacturing process. The objective of the optimization problem is to minimize the P-norm stress or the displacement in the build direction by modifying the design variable in the support domain in order to … WebCompact Space. Compactness is a topological property that is fundamental in real analysis, algebraic geometry, and many other mathematical fields. In {\mathbb R}^n Rn (with the standard topology), the compact sets are precisely the sets which are closed and bounded. Compactness can be thought of a generalization of these properties to more ...
