M. Vujosevic et D. Krajcinovic, CREEP-RUPTURE OF POLYMERS - A STATISTICAL-MODEL, International journal of solids and structures, 34(9), 1997, pp. 1105-1122
The paper focuses on the micromechanical origins and mechanisms of cre
ep failure of epoxy-resins. Microstructure of the material is modeled
by a 2D lattice. The probabilistic nature of the creep deformation pro
cess is based on the kinetic theory of rupture. The macroscopic manife
station of the process: evolution of strain, degradation of stiffness
and endurance are defined in terms of the morphology of the microstruc
ture and processes at the microlevel. (C) 1997 Elsevier Science Ltd.
