The present investigation is concerned with the development of a theory of strength of anisotropic composite materials and the establishment of sound experimental procedures for the confirmation of the predicted results. A general theory is stated whereby the strength of laminated as well as unidirectional composite materials subjected to any state of combined stress can be predicted once the basic strength characteristics of a unidirectional layer have been determined.The transversely… 

Strength Characteristics of Composite Materials.

Abstract : The strength characteristics of quasi-homogeneous, nonisotropic materials are derived from a generalized distortional work criterion. For unidirectional composites, the strength is

Numerical and Experimental Investigation of Carbon Fiber Composites Subjected to a Discrete Source of Damage

The paper investigates the effect of a discrete source of damage on the loading capacity and failure strength of composite materials. First, the effects of varying fiber orientation on the

Application of Homogenization Theory and Limit Analysis to the Evaluation of the Macroscopic Strength of Fiber Reinforced Composite Materials

The macroscopic strength domain of a composite material reinforced by long, parallel fibers is, in general, unknown but for its theoretical definition. In this note it is shown how a homogenization

The structure and mechanical properties of composite materials

The mechanical behaviour of composite materials is examined. As far as is possible, the subject is discussed in terms of general principles, and the aim throughout has been to relate the behaviour of

Analysis of Failure Criteria in Laminas Reinforced with Unidirectional Curaua Fiber Fabric

Natural fibers are increasingly used as composite reinforcement in different fields of engineering. Caraua fiber stands out for its good mechanical properties and adherence to resin; however, little

Micro-Mechanics of Failure (MMF) for Continuous Fiber Reinforced Composites:

The micromechanics of failure was developed to predict the failure of continuous fiber reinforced composites. A micromechanical approach using unit cells of square and hexagonal arrays was employed



Elastic moduli of laminated anisotropic composites

The present investigation is concerned with the development of a theoretical basis for determining the elastic moduli of laminated anisotropic materials within the framework of the theory of plates
