The recently established approximate size effect law for blunt fracture is shown to agree with test data for aluminum. The data are obtained with three-point bent fracture specimens of depths ranging from 0.25 to 4 in. Non-linear fracture parameters can be obtained by a linear regression based on the size effect law. Thus, the fracture energy can be determined using only the maximum load values from fracture tests, and the R-curve can be obtained as an envelope of fracture equilibrium curves. No measurements of crack length or specimen compliance are needed.
