Abstract:

The major part of the scientific work reported here, has been concerned with quantification of the concept of imperfect interface, the modifications of the theory of composite materials for imperfect interface and evaluation of the effect of various kinds of imperfect interface on various properties of various composite materials. In addition a study of the effect of matrix nonlinearity and imperfect interface on the critical compressive stress of unidirectional fiber composites has been performed. The work included the following 1 Thermoelastic properties of fiber composites with imperfect interface 2 Composite materials with viscoelastic interphase 3 Micromechanics aspects of damage in composite materials 4 The spherical inclusion with imperfect interface conditions 5 Thermoelastic properties of particulate composites with imperfect interface and 6 Effect of matrix nonlinearity and imperfect interface on compressive strength of fiber composites.
