Inhaltsangabe

Anders als der Titel vermuten lässt, beschränkt sich das Buch nicht auf Kollisionsmechanik, sondern erläutert im Wesentlich die in PC-Crash verwendeten Modelle, Stand Anfang der Nuller Jahre. Konsequenterweise wird im Rahmen der Kollisionsmechanik vor allem die Vorwärtsrechenmodelle erörtert, während die Rüchwärtsrechnung unter Simplified methods for impact dynamics calculation nur kurz gestreift wird.

This book includes on its 330 pages the entire basic knowledge of the impact dynamics theory. The major part of the book deals with the vehicle dynamics and the impact of vehicles. Thereby impact models are as well presented as the perspective methods for impact dynamics calculation. The book includes 50 pictures, 280 graphs and 150 diagrams. The Book is published in English only.
