Uzair Ahmed Dar and colleagues investigate the mechanical and failure behavior of injection molded aviation standard optical grade polycarbonate (PC) through uniaxial tensile testing. The effect of different injection molding process parameters, including injection velocity, packing pressure, cooling time, mold temperature, and melt temperature, were determined in order to observe their effect on yield and post‐yield behavior of PC. The image shows the digital optical images of the fracture surface of PC specimens failed under different deformation rates. (DOI: 10.1002/app.44474 )
