High temperature polymer creep simulation of aluminum alloy stress-strain distribution using photoelastoplastic stress measurement
Test program for cap section mesh fabrication in prototype space erectable satellite development
Machining technique produces consistently satisfactory plane-parallel optical surfaces for pressure windows, made of plexiglass, required to support a photographic study of liquid rocket combustion processes. The surfaces are machined and polished to the required tolerances and show no degradation from stress relaxation over periods as long as 6 months.
Manufacturing modifications, and glass filler additions for dip resin used in honeycomb structures
Photoelastoplastic method using creep and stress characteristics of epoxy resins under thermal cycle, discussing stress-strain behavior
Fracture theory for amorphous high polymers below glass transition temperature, considering viscoelastic effects on structural defect stress concentration

Small units of standard glass apparatus held together by short lengths of transparent heat-shrinkable polyolefin tubing. The tubing is shrunk over glass O-ring type connectors having O-rings but no lubricant.
Equations for solving initial and boundary value problems in elastoplastic flow in longitudinally stressed, axisymmetric notched rods
Axial slit effects on residual tensile strengths of polyethylene terephthalate film and fabric cylindrical shells
Bending analysis of elastoplastic circular plates for small deflection and axisymmetric loadings and support conditions, based on Kirchhoff hypothesis
Elastoplastic flow equations character in three independent variables, noting solution methods for initial and boundary value problems
Metallic coating directly sprayed on electronic modules provides simple and reliable lightweight protection against radio frequency interference. A plasma arc may be used. Aluminum and copper are the most effective metals.
Hexagonal and nonhexagonal cell phenolic honeycomb structures as energy dissipating material for spacecraft construction
Analysis of supported circular plate under impulsive loading
