| A general tension-compression-compression ;Tensile strength values from the CCATT are compared to experimental results from other tests such as the uniaxial tensile test and the split cylinder test. CCATT results are analyzed using Weibull theory to measure material reliability and to develop characteristic stresses for construction design.;Failure analysis using fractography was conducted on fractured cementitious materials and composites. The failure analysis on test specimens correlated well with FEM stress distributions and with the principal stress ratio. The observed fracture behavior (fracture patterns) was correlated to different strength regions of the model. Additionally, a failure model of fiber wrapped cementitious composite is developed.;Using data on load-extension behavior from the UTT and ultimate strength from the CCATT models for fiber wrapped cementitious composites were developed. These models predict the mechanical behavior of fiber sheets subjected to cycles of wetting and drying in a simulated seawater environment; therefore, the tensile strength using the CCATT is applicable to a wide range of brittle materials including cementitious composites. |
