N2 - The objective of this work is to investigate the interlaminar fracture and damage behavior of woven glass fiber reinforced polymer (GFRP) laminates for mixed-mode bending (MMB) configuration at cryogenic temperatures. The crack length corresponding to critical load is determined using measured specimen compliance of the damage states via finite element analysis (FEA), and the critical mixed-mode energy release rates of MMB specimen at room temperature (RT), liquid nitrogen temperature (77 K) and liquid helium temperature (4 K) are calculated. The values of the critical energy release rate (mixed-mode interlaminar fracture toughness) obtained from the beam theory and FEA are then compared. A FEA coupled with damage is also employed to study the damage distributions within the MMB specimen. Moreover, the results for the special cases of pure mode I and mode II loading of woven GFRP laminates are presented.
