...JT Tzeng Interference stress is an important design factor for press-fitted cylinder applications such as flywheels and pressure vessels, which may decrease over a period of time. Stress relaxation and creep in press-fitted composite cylinders are investigated based on anisotropic viscoelasticity...

...-Tgtemperatures. These compliance terms were shown to be affected by physical aging. Aging time shift factors and shift rates were found to be a function of temperature and applied stress. KEYWORDS: physical aging, composite materials, viscoelasticity, creep compliance, superposition Design and trade studies...

...G Yaniv; O Ishai The hygrothermal effect on time dependent mechanical behavior of a model of nonsymmetrical bonded fiber-reinforced plastic (FRP)/aluminum system was investigated analytically. It was found that a linear viscoelastic closed form solution is sufficient for the prediction of model...
