Mixed-mode fracture behavior of glass fiber reinforced polymer concrete
AbstractFracture toughness of chopped strand glass fiber reinforced particle-filled polymer composite beams was investigated in Mode I and Mode III loading conditions using three-point bend tests. Effects of crack angles on fracture behavior were also studied. The specimens, which have inclined crack at an angle θ to the axis of the specimens, were used to carry out the tests. The specimens were tested with inclination angles 30°, 45°, 60° and 75°. The results are compared with the values of KIC obtained using conventional (θ=90° ) specimens. In addition, J integrals were also determined. JIC increases continuously with increasing in crack angle from θ=30° to θ=90°. In contrast, JIIIC decreases with the crack inclination angle θ from 30° to 90°.
