The book represents the proceedings of a Symposium on Mechanics of Composite Materials held in 1982. Since the mechanics of composite materials is very fast developing a symposium on this topic is pointing up the state of the art, the open problems, the various possible approaches etc. The present symposium proceeding is without doubt a very valuable one. Micro- and macromechanics problems, static and dynamic problems, damage and fatigue, theoretical and experimental aspects, linear and nonlinear behaviour, particulate as well as short and long fiber composites etc., have been discussed, thus covering practically all aspects of composite mechanics.
The contents is shortly the following: In the two sessions devoted to “Analysis of properties” the following papers were presented: R. M. Christensen discussed in a concentrated and comparative way the methods for determination of the effective coefficients, using various geometrical models for inclusion distributions. The influence of microstructure on the thermoelastic and transport properties of particulate and short-fiber composites is presented by R. L. McCullough. E. Kröner has given an approximate method for finding the effective coefficients and the Green function in the static case of ”statistically homogeneous” media; wave propagation in random elastic media is discussed; the author’s viewpoint is that stress and strain are caused by inertial forces that are correlated to the distribution of elastic parameters.
A methodology for estimating the overall elastic-plastic response of composites which undergo finite plastic deformation is given by S. Nemat-Nasser and T. Iwakuma. Effective elastic-plastic stress- strain relations are derived by J. Aboudi for fiber reinforced composites whose constitutes are elastic-viscoplastic workhardening materials. A review on the recent theoretical studies of elastic-plastic behaviour of fibrous composites was done by G. J. Dvorak who has given also an extension to thermal loading problems. Various damping mechanisms in fiber reinforced laminates are discussed by R. Plunkett.
In the session devoted to “Strength” the following papers were presented: Failure analysis of fiber composite laminates (B. W. Rosen); New data on the strength and stress-rupture of Kevlar-49/Epoxy composites (micromechanical modelling and data interpretation) (S. L. Phoenix and E. M. Wu); Analysis of hybrid, uni-directional laminate with damage (L. R. Dharani and J. G. Gore); Modelling of the failure process in notched laminates (R. S. Sandhu, G. P. Sendeckyj and R. L. Gallo).
Three papers were presented in the session on “Dynamic Properties”: Variational characterization of waves in fibre reinforced materials (J. R. Willis); Harmonic waves in a periodically laminated medium (S. K. Datta, A. H. Shah and H. M. Ledbetter); Computational Methods for eigenvalue problems in composites (C. O. Horgan).
Two sessions were devoted to “Laminates”. Here the following topics were discussed: Elastic response of composite laminates (S.R. Soni and N. J. Pagano); Nonlinear effects of elastic coupling in unsymmetric laminates (M. W. Hyer); Elasticitiy solutions for a class of composite laminate problems with stress singularities (S. S. Wang); Failure characteristics of Graphite-Epoxy structural components loaded in compression (J. H. Starnes, jun. and J. G. Williams); Optimization of composite structures (W. J. Stroud); Mechanics of bimodular composite structures (C. W. Bert and J. N. Reddy); Stresses around pinloaded holes in composite materials (Th. de Jong); Optimization of laminated composite plates and shells (Y. Hirano); An endochronic model for the response of unidirectional composites under off-axis tensile load (M. J. Pindera and C. T. Herakovich); Curved thermal crack growth in the interface of a unidirectional Carbon-Aluminum composite (K. P. Herrmann).
The “Damage and Fatigue” were discussed in a special session. The following papers have been presented: Damage mechanics and NDE of composite laminates (K. L. Reifsnider, E. G. Henneke, W. W. Stinchcomb and J. C. Duke); Fatigue failure mechanics of composite laminates (A. Rotem); The role of matrix cracking in the continuum constitutive behavior of a damaged composite ply (R. J. Nuismer and S. C. Tan); A damage approach to the fatigue of composites (A. Poursartip and P. W. R. Beaumont); Energy release rates of various microcracks in short-fiber composites (M. Taya and T. W. Chou).
In the last session devoted to “Experimental Mechanics” a single paper was presented: Experimental mechanics of composites (I. M. Daniel).
