Composite Specimen Design Analysis. Volume 1. Analytical Studies.

摘要

The anisotropic nature of fiber reinforced composites introduces considerable complexity in testing. Problems arise due to the difficulty in attaining uniform or uniaxial stress states in test specimens. A thorough understanding of the behavior of composited is therefore essential before the test data generated from such tests can be used with confidence. Due to the limited scope of the Phase I effort. Attention was focused in this phase only on in-plane shear test methods. A combined analytical/experimental program was conducted in Phase II to evaluate various test methods for tensile strength, compressive strength in-plane shear and interlaminar shear strength. Appendix A of this part contains the results of studies on compression tests. In-plane and interlaminar shear tests are discussed in Appendix B. Combined stress tests and damage analysis are presented in Appendix C. Appendix D gives the analytical studies performed on some interlaminar fracture toughness tests.
