Lecture Notes in Engineering
The Springer-Verlag Lecture Notes provide rapid (approximately six months), refereed publication
of topical items, longer than ordinary journal articles but shorter and less formal than most
monographs and textbooks. They are published in an attractive yet economical format; authors or
editors provide manuscripts typed to specifications, ready for photo-reproduction.

Preface
These proceedings contain the texts of 37 contributions presented at the International Conference
on Engineering Optimization in an Industrial Environment, which took place on 3 - 4 September
1990 at the Karlsruhe Nuclear Hesearch Center, I~H Germany.
The presentations consisted of oral and poster contributions arranged in five sessions:
• Shape and layout optimization
• Structural optimization with advanced materials
• Optimal designs with special structural and material beha viour
• Sensitivity analysis - Programme systems
• Optimization with stability constraints - Special problems
The editors wish to express their appreciation to all authors and invited speakers for their in-
teresting contributions.
The proceedings cover a wide range of topics in structural optimization representing the present
state of the art in the fields of research and in the industrial environment as well. The editors hope
that this book will also contribute towards new ideas and concepts in a world of ever decreasing
natural resources and ever increasing demands for lighter and yet stronger and safer technical
components.
I"inally, the editors wish to thank all colleagues who helped in the organisation of the conference,
especially Mrs. E. Schroder anq Dr. K.llethge, as well as Mr. A. von lIagen and Mrs. E. Haufelder,
Springer Publishing Company, Heidelberg for the good cooperation and help in the publication of
these proceedings.
