Creep and Fracture in Concrete: A Fractional Order Rate Approach [PDF]
, 2002 The paper analyses the interaction between strain-softening and time-dependent behaviour in the case of quasi-static fracture of concrete. A viscous element based on a fractional order rate law is coupled with a micromecanical model for the fracture ...
