Abstract:

This paper is a contribution to the experimental stress analysis of composite structures made of a matrix reinforced with fibers. The analysis is conducted in oversize transparent models in which the matrix is cast around inserts of different rigidities. The manufacturing of the models is described. Two- and three-dimensional photoelasticity are used for the analysis. Stresses and strains along the interfaces, and near the fiber ends, for different fiber end configurations, are studied in detail. Bonded and unbonded interfaces are analyzed. Two loading conditions are considered restrained shrinkage and mechanically applied loading. Several of the difficulties encountered in the analysis are pointed out. The method developed will have application in the fields of fiber reinforced plastic structures, whisker reinforced metals, auto tires, ceramics and reinforced concrete, among others. Author
