Mixed-mode I/II fracture behavior for adhesively-bonded pultruded GFRP joint under four-point bending

The experimental investigation of mixed-mode I/II fracture behavior for the adhesively-bonded pultruded GFRP joint was performed with the four-point single leg bending (4SLB) test. Cracks initiated and propagated in mat layer of the pultruded GFRP laminate for 4SLB specimens with three different thicknesses of upper adherend. The compliances of 4SLB specimens were experimentally and numerically determined. The extended global method was used for...
