Strength Prediction of Fiber Reinforced Plastics with a Hole Under Compression-Tension

Study on the influence of preload on the three-point bending limit load of CFPR countersunk bolt connections

“…Liu Longquan et al [9] experimentally and numerically investigated the combined and interactive effects of bolt hole fit conditions and fastener preload on the load carrying capacity of single-lap composite titanium bolted joints, and proposed a three-dimensional finite element progressive failure analysis model, finding that proper bolt hole fit conditions and preload can improve the bolt hole contact conditions of loaded joints, which in turn delays the fiber damage around the fastener holes and ultimately increases the load carrying capacity of the joints. Soltis et al [10] solved a polynomial approximation solution for the in-plane stresses near the holes for orthotropic anisotropic laminates containing holes under biaxial loading, which was in good agreement with the experimental values. B. Egan et al [11] presents a stress analysis of single-bolt, single-lap, countersunk composite joints with variable bolt-hole clearance.…”

Tensile Strength and Fracture Behaviors of Complex GFRP Composites with a Central Hole

“…Tan [6] presented a modified first-ply failure criterion to express the characteristic damage zone as a function of the opening length and opening aspect ratio for the study of the notched composite specimen. Soutis et al [7] used a fracture mechanics model of quasi-isotropic material to estimate the damage initiation, growth, and final fracture of carbon fiberepoxy plates with an open hole subjected to biaxial compression-tension static loading. These research works are mainly concentrated on the case of simple structure reinforcement like unidirectional fiber-reinforced laminate.…”
