    摘要: A structural analysis program which enables easy structural analysis in accordance with a finite element method based on data representing a two-dimensional shape. A two-dimensional model of a structure is produced in response to a manipulation input which designates a material arrangement pattern and a thickness of each layer of the structure. A three-dimensional model is produced by adding the designated thickness of each layer to the material arrangement pattern of the layer so as to make the material arrangement pattern three-dimensional and stacking the three-dimensionalized material arrangement pattern of each layer. A finite element model is produced by dividing the three-dimensional model into a plurality of voxels. The computer performs structural analysis based on the produced finite element model. Thereby, an analysis result of a multilayer structure defined by the two-dimensional model is obtained.

    摘要: An article under inspection is rotated at pre-set angular increments which total more than 360.degree., to divide the figure inscribed on the curved surface of the article into plural fractions. Selected picture fractions which discard redundant overlapping picture data, is synthesized into picture information indicative of one full-format picture based on which the figure inscribed on the curved surface of the article. Acceptability is determined automatically and quantitatively as compared to the conventional functional inspection and is performed without regard to the difference in skill from one operator to another. Recognizing the characters or symbols inscribed on the curved surface of the article under inspection one by one based on the information of the synthesized full-format picture, allows a comparison of the character string consisting of the recognized characters or symbols to a pre-set control character string.
