The viscoelastic and physical aging responses have been analyzed for an amorphous poly(ethylene naphthalate) (PEN) using uniaxial tension stress relaxation
The U.S. Federal Government has a strong role in metrology R&D in the U.S because of its importance to the nation's economy and the Constitutional authority
Nobel laureate Phil Anderson wrote in Science in 1995 that the glass transition remains the deepest and most important unsolved problem in solid state physics
The effects of the thickness of the thermally grown oxide on residual thermal stresses in a plasma-sprayed thermal barrier coating were numerically simulated in
A liquid couplant is usually necessary between the transducer and the specimen for ultrasonic crack detection and thickness gaging. This work demonstrates the
The perovskite phase SrPbO 3 is important as a buffer and indicator of PbO chemical potential (at fixed p O2 ) according to the reaction: 2 SrPbO 3 --> Sr 2PbO
A variety of characterization techniques have been investigated to study surface and subsurface damage in single-crystal sapphire. To characterize the damage in
