Abstract: This study analyzed the effect of central hole-notch size on the notched tensile strength of organosheet composite material. Organosheet is a novel long discontinuous fiber-reinforced polymer composite produced using 1” long glass fiber, which is incorporated within an in-situ polymerized polyamide 6 (nylon) matrix. A finite-element computational model was developed to predict the notched tensile strength and validated against experimental results. The continuum damage modeling was employed to analyze the failure behavior of the notched fiber reinforced PA6 organosheet. The notched tensile strength was numerically modeled as a function of the notch size using the failure criteria of notched material and compared to the experiment and simulation results. The developed progressive failure modeling was capable to simulate the variability of notched tensile strength and the failure behavior. The proposed theoretical models can be used to predict the notched tensile strength for different notch sizes in organosheet composites.
