...Rolf Sandström; Fangfei Sui For a long time, only empirical models existed for creep curves in the tertiary stage. To understand the role of creep damage, including changes in the dislocation structure, cavitation, and necking, basic models that do not involve adjustable parameters have, however...

...F. Addiego; J. Di Martino; D. Ruch; A. Dahoun; O. Godard; S. Patlazhan Cavitation-induced deformation mechanisms in neat semicrystalline polymers, i.e., crazing, and in the derived composites, i.e., particle-matrix debonding, are generally activated during the transition between viscoelastic...

...–Mechanical Modeling of Polymers and Composites,” Polym. Sci. Ser. A, 48, pp. 1004–1013) of semicrystalline polymers. It is supposed that increase in the interlamellar nanovoid volume fraction results in speeding-up the plastic flow rate while decreasing cavitation rate. Consequently, a proper fitting...

...Isamu Riku; Koji Mimura; Yoshihiro Tomita In rubber-blended polymer, the onset of cavitation in the particles relaxes the high triaxiality stress state and suppresses the onset of crazing in the polymer. As a result, large plastic deformation is substantially promoted compared with single-phase...

... that accounts for craze initiation, growth, and breakdown mechanisms is employed. An energy-based criterion is used for cavitation induced cracking that can lead to fiber/matrix debonding. The role of voids is clarified by conducting a comparative study of unit cells with and without voids. The effects...

... in the absence of cavitation. For the case of a complex macroscopic stress state, such as would be imposed during metal working, the micromechanical analysis comprised yield criteria for the hard and soft colonies, equilibrium conditions, and a self-consistent estimate of the strain partitioning between...

...A. Sahaya Grinspan; R. Gnanamoorthy A new surface modification process was developed to introduce compressive residual stresses at the surface of components. In this process, instead of oil droplets a high-velocity cavitation jet (cloud of oil bubbles) impinges on the surface of the component...

...Hitoshi Soyama, Mem. ASME, Professor Cavitation impact from a cavitation jet, which is formed from bubbles induced by a high-speed water jet in water, can be used for surface modification in a similar manner to shot peening. A cavitating jet is normally produced by injecting a high-speed water jet...
