Unloading-Reloading Sequences and the Analysis of Mechanical Test Results for Continuous Fiber Ceramic Composites

Source

The introduction of intermittent unloading — reloading cycles during mechanical testing is an extremely powerful tool to assist in the interpretation of the mechanical response of a material to the imposed loading conditions. This technique has a potential as a probing method in material characterization which has been vastly underestimated, particularly in the case of continuous-fiber ceramic composites (CFCCs), where, in addition to helping in the description of damage development, it can yield important information on fiber-matrix interfacial phenomena as well. The present contribution highlights the results obtained from the incorporation of unloading-reloading cycles during uniaxial strength, creep and fatigue tests on selected 2D woven CFCCs at room and elevated temperatures. Some implications for the modeling of the mechanical behavior are indicated.
