Characterization of Mixed-Mode Fracture Testing of Adhesively Bonded Wood Specimens
… usefulness of performing mixed-mode tests with a dual-actuator load frame. The material systems evaluated experimentally involved yellow-poplar (Liriodendron tulipifera), a hardwood of the Magnoliaceae family, as adherends and two different adhesives: a moisture-cure polyurethane (PU) and a …

Fracture and plasticity characterization of DH-36 Navy steel
… were performed on butterfly specimens using the dual actuator loading frame. Fracture surface strains were measured using digital image correlation. Local fracture strains were obtained by using an inverse engineering method of matching measured displacement to fracture with computer simulations. …

Control of AFMs in contact mode
… closed loop response of AFM systems in single actuator as well as in dual actuator configurations is evaluated. The emphasis is on the underlying structure corresponding to each configuration and not on a particular system tuning. In this regard, the bounds on achievable performance in each …

Testing and prediction of failure of AHSS sheets at Die Radius and Sidewall using novel fracture apparatus
… to fit the Impact and Crashworthiness Lab's dual actuator custom-made loading frame that has force or position control. The strip is pre-bent into an elbow configuration and fastened by the vertical and horizontal grips. One end of the metal strip is subjected to a predefined constant …

Crack path selection and shear toughening effects due to mixed mode loading and varied surface properties in beam-like adhesively bonded joints
… investigations are also performed. A dual actuator load frame (DALF) is used to test beam-like bonded joints in various mode mixity angles. Constant mode mixity angle tracking, as well as other versatile loading functions, are developed in LabVIEW® for use with a new controller system. …
