The elastic properties of glass reinforced dental composites
Autor: J. Lawrence Katz, Surendra Singh, J.A. Tesk, J. Antonucci, R. W. Penn
Publikováno v: Journal of Non-Crystalline Solids. 102:112-116
Enamel and dentin are materials of complex structure. To replace the lost part of a functionally damaged tooth requires materials which have similar esthetics and physicochemical properties. The elastic properties of the materials are considered to b

The Scaling Law for Finite Torsion of Elastic Cylinders
Autor: R. W. Penn, E. A. Kearsley
Publikováno v: Transactions of the Society of Rheology. 20:227-238
The torque and forces normal to the end surfaces of cylinders of natural rubber were measured as a function of the angle of twist. The measurements were repeated on small cylinders cut from the larger cylinders to insure that the tests were on identi

Time-dependent failure of a polyolefin rubber candidate material for blood pump applications
Autor: R. W. Penn, Gregory B. McKenna
Publikováno v: Journal of biomedical materials research. 14(5)
Failure behavior of a polyolefin elastomer which is a candidate material for blood pump applications has been studied under uniaxial and equibiaxial test conditions. Both static and dynamic (fatigue) testing were performed to study four aspects of ma

Microstructure and Elastic Properties of Dental Resin and Resin-Based Glass-Reinforced Composites: XRD, SEM and Ultrasonic Methods
Autor: J. A. Tesk, R. W. Penn, J. Antonucci, Surendra Singh, J. Lawrence Katz
Publikováno v: MRS Proceedings. 110
The load-bearing ability of dental restorative materials under cyclic high-stress applications depends upon mechanical properties established by the composition and microstructure. The microstructure and the elastic properties of neat resin and two r

The effect of surface preparation on metal/bone cement interfacial strength
Autor: R. W. Penn, Kirk J. Bundy
Publikováno v: Journal of biomedical materials research. 21(6)
This study is concerned with finding practical ways for strengthening metal/bone cement (M/BC) interfaces via surface alterations and identifying fundamental mechanisms underlying M/BC adherence. Shear strengths have been inferred from torsion tests
