Rate dependent fracture behavior of highly cross-linked epoxy resin

Abstract:

The fracture behavior of highly cross-linked epoxy resin under plane strain conditions for crack tip strain rates spanning over four orders of magnitude (10-4 −10-1 s−1) has been examined. The plane strain fracture toughness initially decreases with increasing crack tip strain rate ( ∊ ) and saturates at ∼ 0.8 MPa-m−0.5 after ∊ ∼ 0.02 s−1 is attained. For all the fracture specimens, a fracture process zone (FPZ) forms ahead of the sharp pre-crack prior to catastrophic failure due to the int...
