This volume presents a selection of 434 letters from and to the Dutch physicist and Nobel Prize winner Hendrik Antoon Lorentz (1853–1928), covering the period from 1883 until a few months before his death in February 1928. The sheer size of the available correspondence (approximately 6000 letters from and to Lorentz) preclude a full publication. The letters included in this volume have been selected according to various criteria, the most important of which is scientific importance. A second criterion has been the availability of letters both from and to Lorentz, so that the reader can follow the exchange between Lorentz and his correspondent. Within such correspondences a few unimportant items, dealing with routine administrative or organizational matters, have been omitted. An exception to the scientific criterion is the exchange of letters between Lorentz and Albert Einstein, Max Planck, Woldemar Voigt, and Wilhelm Wien during World War I: these letters have been included because they shed important light on the disruption of the scientific relations during the war and on the political views of these correspondents as well as of Lorentz. similar reasons the letters exchanged with Einstein and Planck on post-war political issues have been included. Biographical sketch Hendrik Antoon Lorentz was born on July 18, 1853 in the Dutch town of Arnhem. He was the son of a relatively well-to-do owner of a nursery.

Theoretical physicists allover the world are acquainted with Lande's celebrated computation of the g factor or splitting factor or, more precisely, the magne togyric factor. The so-called anomalous Zeeman effect had intrigued, if not vexed, some of the most distinguished physicists of that time, such as Bohr, Sommerfeld, Pauli, and others. Lande realized that this recalcitrant effect was inseparable from the multiplet line structure - a breakthrough in understanding which he achieved in 1922 at the age of thirty four. It was in the same year that Lande discovered the interval rule for the separation of multiplet sublevels, a significant result that holds in all cases of Russell-Saunders coupling and renders comparatively easy the empirical analysis of spectral multiplets. In the twenties, Lande succeeded in constructing some original concepts of axiomatic thermodynamics by employing Caratheodory's somewhat esoteric approach as his guiding concept. Published in the Handbuch der Physik, his comprehensive treatise, evincing several novel ideas, has become a classic. Lande, Sommerfeld's student though never a true disciple, published two monographs on quantum mechanics that are remarkable for their content and exposition. In this connection it may be apposite to stress that Lande had sub scribed for many years to the (infelicitously named) Copenhagen interpretation.

Der Begriff der Splinefunktionen wurde von I.J. Schoenberg 1946 eingefUhrt. "Spline" ist der Name eines Zeichengerates, welches auf mechanischem Weg Interpolatio- aufgaben lost.

In diesem Band wird die Entwicklung eines auf der Finite-Elemente-Methode aufbauenden Simulationsverfahrens für die Kalt-, Halbwarm- und Warmmassivumformung beschrieben. Das Verfahren liefert detaillierte Informationen über die plastische Werkstückdeformation sowie Wärmeentstehung und Temperaturausgleich bei Massivumformvorgängen. Die Methode basiert auf dem Markovschen Extremalprinzip und ist auf isotrope, inkompressible Werkstoffe beschränkt. Das starrplastische Fließverhalten wurde mit Hilfe des Stoffgesetzes nach Lévy-Mises erfaßt (bei technischen Vorgängen der Massivumformung können die elastischen und temperaturbedingten Formänderungsanteile gegenüber den plastischen vernachlässigt werden). Die Anwendbarkeit des Simulationsverfahrens wurde an Beispielen zum Kalt- und Warmstauchen von Stahl- und Aluminiumquadern gezeigt. Direkte Vergleiche von berechneten mit experimentellen Untersuchungsergebnissen zeigten eine gute Übereinstimmung. Dazu wurde der zeitliche Temperaturverlauf im Stauchkörper an verschiedenen Stellen meßtechnisch erfaßt und mit den Simulationswerten verglichen. Weitere Vergleiche wurden anhand von Kraft-Weg-Verläufen, Werkstückkonturen und visioplastisch bestimmten Vergleichs-Formänderungsverteilungen durchgeführt.
