Unloading-reloading sequences and the analysis of mechanical test results
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 potential as a probing method in material characterization which has been vastly underestimated, particularly in the case of continuous-fibre ceramic composites (CFCC), where, in addition to helping in the description of damage development, it can yield important information on fibre-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 2-dimensional woven CFCCs at room and elevated temperatures. Some implications for the modelling of the mechanical behaviour are indicated.
