Abstract:

The longitudinal strengths of unidirectional discontinuous fiber composites have been calculated based on the concept of perturbation effect and the distortional energy criterion, utilizing the finite-element method. The theoretical results thus obtained are compared with the experimental data as well as the results of shear lag analysis for tungsten-copper, boron-aluminum, glass-epoxy and boron-epoxy composites. Based on the Jackson-Cratchley equations, modified for discontinuous fibers, a formula is also proposed for calculating the strengths of randomly oriented discontinuous fiber composites. The results calculated from this formula are compared with the experimental data for aluminum oxide-aluminum-silicon and glass-epoxy composites. Author
