The Influence of the Bauschinger Effect on the Subsequent Yield Condition

A new biaxial tension testing machine with flat specimens has been designed and constructed to investigate the plastic behavior of metal under biaxial tension. The capacity of this machine is 5 tons and the stroke is 100mm. The specimen is made in cross-shape. Its dimensions were so determined as to make the region of homogeneous plastic deformation in the middle of the specimen as large as possible. The determination of the stress in the specimen was found possible by the use of the equivalent sectional area.By assuming the yield point as the stress of a permanent set of 200×10-6, an initial and three subsequent yield surfaces were experimentally determined with eleven brass specimens. The following results were obtained from this experiment.The initial yielding follows Mises condition. After prestraining in the principal stress direction:(1) The subsequent yield surfaces are translated in the direction of prestrain.(2) The subsequent yield surfaces do not expand isotropically in any direction.(3) The expansion of subsequent yield surfaces was found quite small.

The Subsequent Yield Surfaces after Proportional Preloading of the Tresca-type Material

The adhesive strength of a butt-type specimen of two cylinders is experimentally studied. Combined stresses are applied on the adhesive layer by subjecting the specimen to combined axial load, torsion and internal pressure. The effects of the surface roughness, the thickness of adhesive layers and the combined stresses on the adhesive strength are examined for the specimens of various metals bonded with epoxy resin. The adhesive failure locus under the combined stress state are represented by a polynominal equation of stress tensors.
