This study examines the effects of physical aging on the fracture performance of polycarbonate materials, specifically comparing extruded sheets and injection molded bars. It utilizes methods such as the essential work of fracture (EWF) and strain energy density to analyze changes in fracture toughness with aging time and temperature, revealing that aging increases the brittle-ductile transition temperature. The findings indicate that the aging process leads to a decrease in fracture toughness, contradictin
