COMPOSITE LOAD TESTING METHOD AND SPECIMEN FOR COMPOSITE LOAD TEST

摘要

PROBLEM TO BE SOLVED: To perform an accurate composite load test of a structural member in a simple method.;SOLUTION: In the composite load testing method, axial stress and shear stress are applied to the following specimen 1 by applying a tensile load or compressive load in a load applying direction, and a breaking load of the specimen 1 is measured. Here, the specimen 1 has, in a center part of a flat plate, an elliptic hole 2 whose major axis or minor axis forms an angle larger than 0° and 30° or smaller with the load applying direction, or the specimen 1 is a rectangular flat plate made of a fiber-reinforced resin base material, in which the fiber orientation method of the fiber-reinforced resin base material forms an angle larger than 0° and 30° or smaller with the load applying direction.;COPYRIGHT: (C)2014,JPO&INPIT
