    Using a smartphone acceleration sensor to study uniform and uniformly accelerated circular motions

    Full text link
    The acceleration sensor of a smartphone is used for the study of the uniform and uniformly accelerated circular motions in two experiments. Data collected from both experiments are used for obtaining the angular velocity and the angular acceleration, respectively. Results obtained with the acceleration sensor are shown to be in good agreement with alternative methods, like using video recordings of both experiments and a physical model of the second experiment.Castro-Palacio, JC.; Velazquez, L.; Gómez-Tejedor, JA.; Manjón Herrera, FJ.; Monsoriu Serra, JA.

    In this work, the hybrid interface between metal and thermosetting polymer matrix composite was studied via experimental and numerical investigations. Hybrid laminates, whose constituents are aluminum foil, carbon fabric and epoxy matrix, were manufactured using the vacuum assisted resin transfer molding process. Chromic anodization was used to treat the surfaces of the aluminum foil prior to fabricating the hybrid laminates. The mode-I dominated delamination behavior was studied using the double cantilever beam tests at both room (25oC) and elevated (60oC) temperatures. Distributed strain profiles were measured on both the top and bottom of the specimen using Rayleigh backscattering fiber optics technique. Finite element analysis was performed to assist with the analysis and interpretation of experimental results. Load-displacement and strain profiles measured from experiments were compared with values obtained numerically. Good agreements between the experimental and numerical results were observed.Aerospace Structures & MaterialsAerospace Engineerin
