Produktbeschreibung

The first IUTAM Symposium on Creep in Structures was held in Stanford, Cal. 1960 (Proceedings, ed. N. J. HOFF, Springer-Verlag 1962). That meeting reflected an intense research activity in the field of structural creep, and many important results were pre sented. In spite of this progress design rules for high temperature equipment are still often inadequate. Design against creep deformation and creep rupture is all too often based only oli experience and intuition. With technological processes moving into ever higher temperature regions the effects of creep must be given steadily increasing attention. The IUTAM Bureau in 1967 decided to arrange a Second Symposium on Creep in Structures, to be held in Gothenburg under the chairmanship of F. K. G. ODQVIST. This meeting was to take stock of the progress made in the ten years since the first symposium. Notable advances in the establishment of a sound phenomenological theory, refined experimental techniques and several new methods ofstructural analysis of shells in the creep range gave impetus to this second symposium. Problems of rupture and stability under complex loads had been studied and many new results in these fields were presented and discussed. Attendance was strictly limited to persons active in the field covered by the symposium. Financial support was generously provided by IUTAM, Chalmers University, the Swedish Board for Technical Develonment and four Swedish industrial companies (ASEA, Sand mens Jernverk, Saab-Scania, Volvo).
