A continuum damage mechanics model for ud composites with the evolution law based on the damage driving force concept
A continuum damage mechanics model for ud composites with the evolution law based on the damage driving force concept
The present paper is the implementation of the roadmap as set in [1] with necessary extension, which further develops the previous continuum damage mechanics (CDM) theoretical model for UD composites into a fully functional model in the form of finite element analysis user-defined material subroutine (UMAT). Based on its original capability of modelling matrix cracking damage, the present CDM model benefits from the integration of suitable damage initiation criteria, damage modelling during reloading after unloading and the modelling capability for various abrupt failure modes, making it capable of rationally defining the onset, evolution and orientation of damage under all possible loading conditions while being able to predict abrupt failures like fibre failure. The application of the CDM model requires a number of suitably defined damage related material properties which are extracted from carefully designed experiments on laminates. To verify the model, applications have been made to quasi-isotropic laminates for which experimental results have been obtained and comparisons are made against the predictions from the CDM modelling. In the future, this CDM model will be implemented for yarns inside 3D textile composites where it should serve as a necessary material subroutine to be used in the unit cell analysis for textile composites, which will support the data point generation phase in the development of the artificial neural network system for the prediction of textile composite properties as mentioned in [2].

Abstract
The present paper is the implementation of the roadmap as set in [1] with necessary extension, which further develops the previous continuum damage mechanics (CDM) theoretical model for UD composites into a fully functional model in the form of finite element analysis user-defined material subroutine (UMAT). Based on its original capability of modelling matrix cracking damage, the present CDM model benefits from the integration of suitable damage initiation criteria, damage modelling during reloading after unloading and the modelling capability for various abrupt failure modes, making it capable of rationally defining the onset, evolution and orientation of damage under all possible loading conditions while being able to predict abrupt failures like fibre failure. The application of the CDM model requires a number of suitably defined damage related material properties which are extracted from carefully designed experiments on laminates. To verify the model, applications have been made to quasi-isotropic laminates for which experimental results have been obtained and comparisons are made against the predictions from the CDM modelling. In the future, this CDM model will be implemented for yarns inside 3D textile composites where it should serve as a necessary material subroutine to be used in the unit cell analysis for textile composites, which will support the data point generation phase in the development of the artificial neural network system for the prediction of textile composite properties as mentioned in [2].
