摘要：
The influence of geometrical discontinuities on the stress distribution is critical for design applications. A novel type of composite, named glass-fiber-cotton reinforced monomer casting nylon (GFCR MC-nylon), is prepared, and the circular-hole stress concentration of a GFCR MC-nylon plate is investigated via the digital image correlation technique (DIC). The experimental results show that the stress concentration factor (SCF) of the composite varies with the diameter of the circular hole and stress intensity. A novel finite element model is established to investigate the influence of glass-fiber (GF) length on SCF. The simulation results show high agreement with the experimental results. The findings provide the basis for the structure design of fiber-cotton reinforced composite. © 2018, Mathematical Sciences Publishers.
