The strength of material is usually determined from the fracturing load through brief calculation formula assuming simple stress distribution in the specimen. However, complicated stress distribution may be caused in the specimen under some kind of shear test.
The authors have performed single-plane shear test using the rotary-die-type simple shear testing apparatus, which was suggested from I. B. G. standard plan and improved by Kobayashi. They have analyzed the boundary conditions between the specimen and the shearing tool and confirmed it by the measurement. Then they have analyzed elasto-plastic behaviour of the specimen considering the above conditions.
It is suggested from the results obtained that inclination between the vertical plane and the shear-plane prescribed must not be far from 27°50' for significant shear test.
