Sheet Stamping

Metal sheet Stamping forming is an important material forming process, especially in the automobile industry. Using the advanced FEM simulation technology, precise analysis of the metal sheet stamping forming process becomes possible, which provides the scientific evaluation of the process design and die design in sheet stamping forming. So the paper chooses a topical auto drawing part-auto indoor-still part and applied the CR340LA steel to have stamping numerical simulation test by the numerical simulation analyzing software-Dynaform. In the stamping numerical simulation test, the best binder holder force values, stamping speed values and the spring back forecast results are got. Then the springback forecast results of the numerical simulation analysis tests are applied to the actual production to overcoming the spring back effectively, and the successful products are got.

During archaeological research carried out from 2009 to 2016 in the Church of St. Nicholas in Gniew, a set of three metal buckles was found. Then, in 2017, excavations were conducted in crypts of the Church of the Nativity of the Blessed Virgin Mary in the village of Piaseczno, in the Gniew District. Two other pairs of buckles were uncovered at this site. All the buckles found differ considerably. Thanks to this, one can get an impression that apart from holding the shoe on the foot, they also served decorative purposes. One can distinguish two main types of buckles: those made of iron and those made of a copper alloy. The latter, considering ornaments, could be more valuable than their iron counterparts. Regardless of the alloy used, manufacturing techniques differed, some of which were those used in the case of buckles from Gniew and Piaseczno: wire forging, cutting out of thick metal sheet, and folding thin metal sheet. On account of their jewellery-like character, this small collection of buckles discussed could be bequeathed, while most grave shoes were only fastened with tailor’s pins or put on the feet of the dead without fastening. This practice particularly concerned shoes with textile uppers, which mostly meant women’s shoes. It may suggest that the items in question were rather owned by men. The buckles described could be thus elements of the everyday attire. Issues connected with a formal and typological interpretation of the buckles found indicate interpretive problems faced by archaeologists dealing with these aspects of costume studies. Modern shoes, due to the scarcity of artefacts in archaeological collections, remain mysterious and puzzling objects.

AbstractThe purpose of this paper is to report on an expert system in design that screens for potential hazards from environmental chemicals on the basis of structure-activity relationships in the study of chemical carcinogenesis, particularly with respect to analyzing the current state of known structural information about chemical carcinogens and predicting the possible carcinogenicity of untested chemicals. The structure-activity tree serves as an index of known chemical structure features associated with carcinogenic activity. The basic units of the tree are the principal recognized classes of chemical carcinogens that are subdivided into subclasses known as nodes according to specific structural features that may reflect differences in carcinogenic potential among chemicals in the class. An analysis of a computerized data base of known carcinogens (knowledge base) is proposed using the structure-activity tree in order to test the validity of the tree as a classification scheme (inference engine).
