From the author: Fracture behavior of PBT/PC blend was studied at room temperature using two specimen geometries (SENT and DENT) and a wide range of specimen sizes and crosshead speeds. It was found that the fracture of all SENT and DENT specimens is completely ductile and stable. A linear relationship was obtained between the specific total work of fracture, [w.sub.f], and the ligament length, L. Extrapolation of this linear relationship to zero ligament length gave the specific essential work of fracture, [w.sub.e], which for PBT/PC blend was 35 [+ or -] 5 kJ/[m.sup.2] and was almost insensitive to geometry and the dimensions of test specimens as well as testing rate.
