<p>A material testing apparatus (10) for applying selected force and moment loads to a test specimen (12) includes a base assembly coupleable to the test specimen (12). The base assembly (14) includes a support member (20) and a first load generating mechanism adapted to apply a first load to the test specimen (12). A reaction structure (16) reacts the first load applied to the test specimen (12). The reaction structure (16) includes a reaction support (6) joined to the support member (20). A moveable head (62) is coupleable to the test specimen (12) and is moveable relative to the reaction support (60). A second load generating mechanism (64, 120) is coupled to the moveable head (62) and the reaction support (60). The second load generating mechanism (64, 120) is adapted to apply selected loads to the test specimen (12) in at least two degrees of freedom.</p> |
