1057 Behavior of a low-carbon steel film under cyclic shear load
Details
Pure mode II propagation was realized under cyclic torsion load in acrylic round bar bonded low carbon steel, and anomalous behavior occurred in the film. In this study, behavior of the film was discussed. As a result, crack occurred in ferrite grain sandwiched in pearlite grains. The propagation behavior of fatigue crack depended on crack length occurring between pearlite grains. Definite deformation was observed in a round bar. But deformation was hardly observed in the film.
