Title: Fatigue Crack Growth and Mechanical Behavior of Double-Edge-Cracked Ti/APC-2 Nanocomposite Laminates

Abstract

The mechanical properties and fatigue responses of double-edge-cracked Ti/APC-2 hybrid nano-composite laminates by tensile and cyclic tests were obtained. The double-edged cracks were cut with the crack lengths of 2.0 mm and 3.0 mm symmetrically and anti-symmetrically. The mechanical properties of symmetrically cracked samples are more detrimentally than those of anti-symmetrically counter parts. The greater the cracked angles, the greater the maximum load, however, the results of crack
