    • PROBLEM TO BE SOLVED: To provide a structural analysis method which enables accurate calculation in a short time with regard to the structural analysis of a member injection-molded using a material containing a filamentary material. SOLUTION: The structural analysis method for the member to be injection-molded using the material containing the slender filamentary material includes a shape acquisition step of obtaining shape information indicating the shape of the member, an element division step (S2) in which the entire shape of the member is divided into a plurality of elements to produce element information indicating each divided element, a thermal analysis step (S3) in which thermal characteristic values indicating the thermal characteristics of the member by carrying out thermal analysis by the use of each element indicated by the element information on the assumption that a heat source is in a part corresponding to the gate of a mold for charging the material to produce thermal characteristic information including it, a conversion step (S4) for converting the thermal characteristic information into physical property information indicating physical property values for carrying out the structural analysis, and a structural analysis step (S5) for carrying out the structural analysis of the member using the physical property information and information indicating each element.

    • PROBLEM TO BE SOLVED: To provide a crack detecting apparatus and a crack detecting method for detecting in a non-contact way cracks not only in the surface of but also inside a measurement object while keeping the object afloat. SOLUTION: A crack detecting apparatus comprises floating means 1 that floats a measurement object 50 in the air, vibrating means 2 that vibrates the floated measurement object 50 up and down, an action detecting device 3 that detects any output of response to the vibrating input of the vibrating means 2 to the measurement object 50, and crack detecting means 4 that detects the presence or absence of cracks in the measurement object on the basis of the output of the action detecting device 3. The floating means 1 and the vibrating means 2 have an under plate 13 each connected to a positive or negative electrode. By applying a voltage to the under plate 13 and thereby electrifying the under plate 13 and the measurement object 50 mounted on the under plate 13 to the same charge, the measurement object 50 is floated in the air and, at the same time, the measurement object 50 is vibrated by periodically varying the level of the input voltage to the electrode.
