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.

Approximate Reanalysis in Topology Optimization : APPROXIMATE REANALYSIS IN TOPOLOGY OPTIMIZATION

Amir, Oded; Bendsøe, Martin P.; Sigmund, Ole

International Journal for Numerical Methods in Engineering — 2009, Volume 78, Issue 12, pp. 1474-1491

In the nested approach to structural optimization, most of the computational effort is invested in the solution of the finite element analysis equations. In this study, the integration of an approximate reanalysis procedure into the framework of topology optimization of continuum structures

Revisiting approximate reanalysis in topology optimization: on the advantages of recycled preconditioning in a minimum weight procedure

Amir, Oded

Structural and Multidisciplinary Optimization — 2015, Volume 51, Issue 1, pp. 41-57

An efficient procedure for three-dimensional continuum structural topology optimization is proposed. The approach is based on recycled preconditioning, where multigrid preconditioners are generated only at selected design cycles and re-used in subsequent cycles. Building upon knowledge regarding
