Sažetak
A multi-scale framework for modelling of intrinsically self-healing FRP composite structures is presented in this work. At the microscale, matrix constituent is modelled using the previously developed and validated micro- damage-healing constitutive model. In this model damage variable reduces the material’s elasticity modulus, whereas the healing variable causes its restoration. Reinforcing fibres are considered transversely isotropic and linear elastic. Hashin failure criterion and progressive damage model are used for modelling of fibre failure and postfailure behaviour. Inhere, the model is implemented in Abaqus/Standard user material subroutine UMAT and validated by means of three point bending (3PB) experiments presented in [1]. Subsequently, the validated model is implemented into Abaqus/Explicit user material subroutine VUMAT and used for numerical experiment of Low Velocity Impact (LVI). The results are presented in this work.
