A computing device includes: a tomographic image acquisition unit that acquires a plurality of tomographic images representing shapes of reinforcing fibers and shapes of resin in a plurality of cross sections obtained when an article containing the reinforcing fibers and the resin is divided in parallel; and a computing unit that calculates a rigidity parameter of each of a plurality of small regions obtained by dividing the article, based on the plurality of acquired tomographic images.

Computing device and computing method for evaluating strength of article formed by 3D printer

To provide an aircraft strength testing apparatus that, using a curved specimen, can produce a desired stress safely and quickly by reliably applying an internal pressure, and moreover allows any resulting damage to be reliably observed. A testing apparatusthat applies an internal pressure, equivalent to a differential pressure between the outside and the inside of a section to be tested of a fuselage of an aircraft, to a curved specimencorresponding to the section to be tested, includes: a pressure vesselbetween which and the specimena cavityis formed; and rodsthat restrain the specimenagainst the internal pressure. The pressure vesselfaces the outer side of the specimen. By reducing the pressure inside the cavity, an internal pressure is applied to the specimen
