| 摘要 |
The present invention relates to an apparatus for testing a specimen having a curved surface, in which a flat shaped specimen having a curved surface is experimented, the apparatus including: a base plate; a plurality of pressurizing parts installed on the base plate facing each other to apply surface pressure to the specimen; and a movement limiting part to limit the specimen from moving in a thickness direction of the specimen, wherein the movement limiting part includes a plurality of lower supporting parts extending from the pressurizing parts to a center of the specimen to support a lower surface of the specimen, and a plurality of upper support parts extending from the pressurizing parts to a center of the specimen and spaced apart from an upper part of the lower supporting part so that the specimen is accommodated between the lower supporting part and the upper supporting part. Therefore, according to the present invention, the apparatus for testing a specimen having a curved surface, which measures a transformation characteristic of the specimen occurring when a weight is applied to a large sized specimen having a curved circumference, and secures highly reliable data, can be provided. |
