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 ...
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 ...
Yield behavior of unoriented and oriented polycarbonate and polypropylene as influenced by temperature
(Elsevier, 1980-05)
The yield behaviors of an amorphous polymer (polycarbonate) and a crystalline polymer (polypropylene) were investigated over certain ranges of temperature. Both polymers were used in an unoriented (isotropic) and an oriented ...
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 ...
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 ...
