The fatigue strength, fracture mechanics, and mechanical properties of
vapor deposited carbon used for components of implanted mechanical heart
valves. (Fortunately, we find this carbon material almost insensitive to
stress cycling.) The atomic modeling of Vegard's Law. Failure analysis.
Use of lenses in antiquity.
The creep resistance and ultra-plasticity of carbon fiber and creep of
carbon-carbon composites. Characterization of rocket nozzle materials. The
biaxial strength of advanced ceramics. Micro-mechanical theories of the
strength of ceramics. Delayed fracture of ceramics.
Fatigue tests of metals under combined stress and development of the
generalized criteria for fatigue strength. Interaction of atomic defects
in anisotropic media. The growth of filamentary crystals and their
