You can download the manuscripts of papers on Archery from this homepage.

The manuscripts of the papers are available in PDF and PostScript format. You need Acrobat Reader to be able to read and print the PDF files. PostScript files can be printed only on PostScript printers or viewed on the screen with GhostView.

If you make a citation to the papers, please refer to the published version in the scientific journal. Notice that the numbering of the Equations, Figures and Tables generally differ from those in the original paper. Therefore, please check these numbers when you really want to refer to Equations, Figures or Tables.

There are three categories. The first two categories are Mechanics of the bow dealing with the behaviour of the bow where the arrow is treated simply as a point mass, and Mechanics of the arrow dealing with the motion of the arrow and where the model for the bow is rather simple. The third category is formed by the papers published in the Journal of the Society of Archer-Antiquaries. Information about the Society of Archer-Antiquaries is given here: SOAA.

These papers deal with the modelling of the dynamics of the bow where the arrow is assumed to be a point-mass which is attached to the middle of the string. A numerical scheme for the solution of the governing equations is developed. Different types of bows are distinguished and their static and dynamic behaviour are studied. The performances are assessed by comparison of quality coefficients such as the efficiency. In the introduction of the PhD-thesis an overview of models for the dynamics of the bow published in the literature is given.

In the article written together with Dr. C. Tuijn (University of Amsterdam, The Netherlands) an experimental set-up is described to measure the velocity of an arrow accurately. This technique was also used by Ide-Teknik, Bertil Olsen. The paper with Dr. C.A. Bergman (Northen Kentucky University and 3D Environmental Services, Inc. 781 Neeb Road, Cincinnati OH 45233-4625, USA) describes the modelling aspects for those who do not like formulae.

In these article I deal with the motion of the arrow when it is released from the bow. The mathematical model is derived by considering the arrow as a vibrating beam with time-dependent boundary conditions. The governing equations are solved numerically. In the second paper our model is compared with a model proposed by Pekalski from Poland who did experiments in addition to modelling. The last paper is a review of published articles on the ``The Archer's Paradox".

The following articles are published in the Journal of the Society of Archer-Antiquaries are written for non-mathematicians. I tried to explain the train of thought with building a mathematical model (without describing it with formulae) and to define quality coefficients which describe the quality of a bow-arrow combination quantitatively.
