Abstract

The aim of this study is to experimentally investigate the open-hole tensile response of pseudo-ductile thin-ply angle-ply laminates and to design laminates with reduced notch sensitivity. Thin-ply angle-ply laminates with [(±26)₅/0]_s2 configuration were tested in both unnotched and open-hole tension and damage was characterized using ultrasonic C-scan. A pseudo-ductile stress-strain tensile response with pseudo-ductile to initial strain ratio of 1 has been achieved in unnotched tensile testing. In terms of open-hole performance, it is shown that 65% of the unnotched yield strength was retained and C-scan imaging revealed that no obvious damage was detected in a specimen interrupted at 95% of ultimate load. In addition, a finite element study suggests that a better performance could be achieved if the pseudo-ductile to initial strain ratio is increased.
