METHODS AND SYSTEM FOR DETERMINING SHEAR ANGLE

摘要

A process (130) for determining an actual shear angle (¸) between an interior wall (30) and a facesheet (22, 24) of a cellular panel (20) using an imaging system (40) is disclosed. The imaging system includes a radiation source (44) and a detector (46) diametrically opposed to the radiation source. The process includes positioning (132) the cellular panel at a tilt angle (Æ) relative to a line (50) extending between the radiation source and the detector, transmitting (134) radiation from the radiation source to the detector through the cellular panel at the tilt angle to obtain an image (62), measuring (136) a projected shear angle (±) in the obtained image, and determining (138) the actual shear angle between the interior wall and the facesheet using the tilt angle and the projected shear angle.
