The Symposium originated in a proposal made in 1969 by Professor A. A. Ilyushin, Moscow. A study group (chairman J. Hult) , appointed by the General Assembly of IUTAM in 1971, suggested in areport to the Bureau of IUTAM in 1972 that the following topics should form the basis of the scientific program: 1) Limits of linearized theories and effective versions of the non-linear theory of viscoelasticity 2) Theory of experimental studies in linear and non-linear viscoelasticity aiming at the determination of consti- tutive equations and conditions of strength and failure under an arbitrary deformation process 3) Experimental and theoretical studies of thermal effects in viscoelasticity taking into ac count thermo-mechanical coupling 4) Novel analytical and numerical techniques for the solution of problems in viscoelasticity and thermo-viscoelasticity. This proposal was accepted by the Bureau, and the following Scientific Committee was appointed: J. HULT, Chalmers University of Technology, Fack, S-402 20 GOTEBORG, Sweden (Chairman) J. F.

The book aims at giving an overview of current methods in engineering mechanics of FRP components and structures as well as hybrid components and structures. Main emphasis is on basic micro and macro mechanics of laminates. Long as well as short fibre composites are studied, and criteria for different kinds of rupture are treated. Micromechanical considerations for material characterization and mechanisms of static ductile and brittle rupture are studied, as well as FRP structures under thermal and dynamic loading programs. Optimum design and manufacture situations are described as well. The book makes designers familiar with the opportunities and limitations of modern high quality fibre composites. Practical engineering applications of the described analytical and numerical methods are also presented.
