Fractographic study of transverse cracks in a fibre composite
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-07)
Transverse fracture of unidirectional fibre composites was studied in a model glass/epoxy composite in which 1 mm-diameter rods had been used in place of fibres. The fracture surface resulting from transverse cracking in ...
Plasticity of brittle epoxy resins during debonding failures
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-11)
A remarkably high degree of plasticity in brittle epoxies during debonding failures is reported. The plasticity is exhibited by the presence of ridges on the debonded surfaces having a width and height above the general ...
The stability of SiO-based ceramics containing ZRO2 and other oxides
(Elsevier, 1983)
Calculations of thermochemical equilibria, using the program SOLGASMIX, have defined the conditions and compositions of SiO-based ceramics in which stable ZrO2 particles can be obtained. The results are compared with ...
Effects of shearing conditions on crystalline orientation and relaxation in polyethylene
(Society of Plastics Engineers, Inc.Wiley Periodiocals, Inc., 1983-02)
The effects of shearing conditions (i.e., shear temperature and shear rate) on the degree of orientation of polyethylene (Marlex 6006) and to what extent the induced orientation could be relaxed were examined in this study. ...
Toughening mechanisms in elastomer-modified epoxies
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1986-07)
The toughening mechanisms of elastomer-modified epoxies are examined by scanning electron microscopy, transmission electron microscopy, and optical microscopy, DGEBA epoxies toughened by various levels of several types of ...
Formation And Characterization of Amorphous Erbium-Based Alloys Prepared By Near-Isothermal Cold-Rolling of Elemental Composites
(American Institute of Physics, 1985)
Texture development in polyethylene II. Unidirectional rolling
(John Wiley & Sons, Inc., 1989-08)
The effect of degree of strain on texture development in high-density polyethylene has been studied by pole figure analysis for unidirectional rolling. The crystallite orientation distribution in rolling textures has been ...
Toughening mechanisms in a multi-phase alloy of nylon 6,6/polyphenylene oxide
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-04)
Toughening mechanisms in a nylon 6,6/polyphenylene oxide (PA/PPO) alloy are studied. This alloy consists of well dispersed PPO particles (containing an elastomeric phase) in a PA matrix. Both crazing and shear yielding ...
Fatigue crack growth retardation inconel 600
(Elsevier, 1984)
The effect of single-cycle overloads on the subsequent fatigue crack growth behavior of Inconel 600 is studied. Overloads ranging from 10 to 50% are applied to a sample undergoing baseline fatigue crack growth at constant ...
The effect of ion beam surface modifications on fatigue crack initiation in polycrystalline nickel
(Elsevier, 1989-08-01)
Flexural fatigue tests at surface strain amplitudes of +/-0.0012 were conducted on polycrystalline nickel to determine the effect of ion beam surface modifications of the Ni/Al system on fatigue crack initiation. An ...
