Book: Optimization of mechanical structures 3rd edition
3rd edition of the book "Optimization of mechanical structures" published by Springer-Verlag in autumn 2020
The aim of the book is to impart the necessary knowledge for the efficient use of mathematical optimization methods in the design and structural layout of components.
It also provides the essential basics for computer-aided design and calculation.
The author includes the latest developments and areas of application in the field of optimization and discusses the advantages and disadvantages of the various optimization approaches. The concrete applications of optimization presented facilitate familiarization with this mathematically demanding field. With the help of the exercises provided, the reader can consolidate what they have learned on their own computer.
In the current 3rd edition, explanations have been revised and current optimization algorithms and methods have been included.
