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.

Discontinuous transformations and averaging for vibro-impact analysis

Thomsen, Jon Juel; Fidlin, A.

Procedings of Xxi Int. Congress of Theoretical and Applied Mechanics — 2004

Certain vibro-impact problems can be conveniently solved by discontinuous transformations combined with averaging. We briefly outline the background for this, and then focus on illustrating the procedure for specific examples: A self-excited friction oscillator with one- or two-sided stops

Near-elastic vibro-impact analysis by discontinuous transformations and averaging

Thomsen, Jon Juel; Fidlin, Alexander

Journal of Sound and Vibration — 2008, Volume 311, Issue 1-2, pp. 386-407

We show how near-elastic vibro-impact problems, linear or nonlinear in-between impacts, can be conveniently analyzed by a discontinuity-reducing transformation of variables combined with an extended averaging procedure. A general technique for this is presented, and illustrated by calculating

Near-elastic vibro-impact analysis by discontinuous transformations and averaging: DCAMM Report 720

Thomsen, Jon Juel

We show that near-elastic vibro-impact problems can be conveniently analyzed by a discontinuity-reducing transformation of variables, combined with an extended averaging procedure that allows small discontinuities. A general technique for this is presented, and illustrated by calculating transient
