Composite materials have been used for several years in thermal protection systems such as reentry vehicle nosetips and heatshields as well as in more conventional aerospace structures such as laminated wings and stabilizers in the latest aircraft. Many composite materials, e.g., ATJ-S graphite, carboncarbon, and graphiteepoxy, exhibit different strength and stiffness behavior in tension and compression. The moduli differences range from 20 for ATJ-S graphite to between 100 and 400 for carboncarbon. The principal objective of the research is to analyze the behavior of solid bodies with different elastic moduli in tension and compression as well as the behavior of laminated plates and shells that have different elastic moduli in tension and compression and lamination asymmetries.
