    FRACTURE SURFACE DIGITIZING OF SPECIMEN FROM DROP-WEIGHT TEAR TEST

  • Original language description

    There is always a need to determine a fraction of the ductile,and respectively, brittle fracture on the fracture surface of specimen examined using a drop-weight tear test (DWTT).Determination of the percentage of ductile fracture (PDF) in accordance with valid national and international recommendations is not entirely unambiguousResults of evaluation show a large scattering for each criterion, and depend on the subjective view of the evaluator. Criteria are complex in nature and are independent of thefracture morphology. The dimensionless areas ratio criterion has been newly proposed for the evaluation of the DWTT specimens.This criterion is given by the ratio of the fracture surface projection into a base plane to the scanned fracture surface.The fracture surface of the DWTT specimen is scanned using a 3D-Cam scanner into a network of discrete points.A fracture surface area is calculated from the sum of the areas of triangles constructed above the element of the projection of fractu
