The parameters which effect the cavitation strain of polymer blends toughened with a shear yield mechanism have been studied by analysis of the stress acted on the equatorial plane of dispersed‐phase particles. As a result, the cavitation strain of polymer blends depends on the Young's modulus and the Poisson's ratio of the dispersed‐phase particles and the matrix and also on the break stress of dispersed‐phase particles. We tried to provide a criterion for selecting the materials used as dispersed‐phase particles which can effectively enhance the toughness of polymer blends. © 1996 John Wiley & Sons, Inc.
