Abstract
A testing arrangement includes a test specimen that is formed of a fiber composite that has first, second, and third groups of fiber ply layers. Each fiber ply layer is curved so as to have an elbow. The elbows are joined back-to-back at a central region to form first, second, and third arms that extend outwardly from the central region. The elbows define a space in the central region, and there is a space-filler within the space. The test specimen is mounted in a testing fixture such that the first and second arms are in four-point bend loading and the third arm is oriented vertically. The testing fixture is actuatable to apply an actuated load. There is an applied load on the third arm. The applied load and the actuated load cause stress in the space-filler for evaluating mechanical behavior of the space-filler.
