**Abstract**
 In this study, the effect of plastic deformability of the matrix phase on the yielding behaviour of the rubber-modified epoxy adhesives was examined. Yield behaviour was measured by use of butt and scarf joints subjected to tensile loading, and to a butt joint with a thin-walled tube subjected to torsional loading. A reactive diluent was used to vary the plastic deformability of the matrix phase. The applicability of Gurson's model was checked by comparing the experimentally-obtained yield stresses in these joints with those calculated by a finite element method. As a result, it was confirmed that the yield stress of the rubber-modified adhesives with different matrix phases could be approximately estimated from Gurson's model. Thus, the effect of plastic deformability of the matrix phase on Gurson's parameter could be discussed. 13 refs.
