A fracture criterion based on the concept of linear notch mechanics for predicting the tensile strength of composites containing stress concentrations is subjected to further experimental scrutinization. An experimental program is presented which examines the effect of hole size on the fracture of FRP plates. This is accomplished by obtaining experimental data on tension tests of FRP plates containing through-the-thickness circular holes for a wide range of sizes. Two kinds of FRP plates were used in the tests: a woven roving glass fabric epoxy laminate and a short glass fiber/polycarbonate laminate. The experiment shows that the maximum elastic stress at the edge of the hole when the specimen fails, σmax, c, is governed by the radius, of hole, ρ, with the exception of very small holes. The characteristic curve of σmax, c against ρ for the plates containing a circular hole agrees with the curve for the notched plates. On the basis of the concept of linear notch mechanics, the experimental results mentioned above can be clearly explained. For very small holes the situation is more complex. The maximum elastic stress at fracture, σmax, c is determined predominantly by the tensile strength of unnotched bars and is independent of the hole size and the width of the plate. It seems likely that the limiting value of the diameter of hole is a characteristic value of the material.
