Abstract : A theoretical investigation of the compressive response of a wire embedded in a matrix is reported. In the first two sections consideration is given to the beam-column behavior of an initially crooked wire embedded in a matrix which is subjected to a state of uniaxial stress. A plot of the effective stiffness of the wire as a function of the wire's initial crookedness is given. Secondly, consideration is given to the possibility of buckling, within the matrix, of a compressively loaded straight wire. A plot of the buckling load of the wire as a function of the ratio of the wire's and matrix's shear moduli is given. Two procedures are developed for the prediction of the lateral support offered to the wire by the matrix. Both procedures are developed by treating the matrix as a three-dimensional elastic solid, however, only the first of the two methods completely satisfies the displacement continuity requirements between the wire and the matrix.
