By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Combined Shape and Topology Optimization

Christiansen, Asger Nyman

Technical University of Denmark — 2015

Simplicial Complex (DSC) method. Consequently, we present a novel method which combines current shape and topology optimization methods. This method represents the surface of the structure explicitly and discretizes the structure into non-overlapping elements, i.e. a simplicial complex. An explicit surface

Combined shape and topology optimization of 3D structures

Christiansen, Asger Nyman; Bærentzen, Jakob Andreas; Nobel-Jørgensen, Morten; Aage, Niels; Sigmund, Ole

Computers and Graphics — 2015, Volume 46, pp. 25-35

We present a method for automatic generation of 3D models based on shape and topology optimization. The optimization procedure, or model generation process, is initialized by a set of boundary conditions, an objective function, constraints and an initial structure. Using this input, the method

Combined shape and topology optimization for minimization of maximal von Mises stress

Lian, Haojie; Christiansen, Asger Nyman; Tortorelli, Daniel A.; Sigmund, Ole; Aage, Niels

Structural and Multidisciplinary Optimization — 2017, Volume 55, Issue 5, pp. 1541-1557

This work shows that a combined shape and topology optimization method can produce optimal 2D designs with minimal stress subject to a volume constraint. The method represents the surface explicitly and discretizes the domain into a simplicial complex which adapts both structural shape and topology
