    Influence of Root Rotation on Delamination Fracture Toughness of Composites by V. Alfred Franklin, T. Christopher, B. Nageswara Rao

    Published 2014-01-01
    “…This paper examines the effect of rotational spring stiffness (K) on the critical fracture energy (GIC) considering nonzero slope at the crack-tip of the DCB specimen by modelling each cracked half as the spring-hinged cantilever beam. The critical load estimates of DCB specimens from GIC are found to be in good agreement with in-house and existing test results of different composite material systems.…”
