Abstract
In the present study, the fracture parameters and crack tip deformation field in continuous functionally graded (FG) glass-filled epoxy composite were experimentally investigated employing digital image correlation. Beams with monotonic variation Young’s modulus and cracks along the variation were studied. Two specimens with single edge cracks were examined in different crack positions in relation to the increase or decrease in Young’s modulus. The mechanical properties of the FG composite were extracted by performing a tensile test of samples machined according to ASTM D638. The stress intensity factors and T- stresses (high order term) were evaluated from the displacement field by adopting William’s series. This is the first research which calculated the mixed-mode stress intensity factors, as well as the T-stress in beam made of continuous epoxy glass functionally graded beam using DIC technique. The crack tip was elastically protected on the compliant side of the specimen unlike the crack on the stiffer side.
