Modeling of the stress-strain behaviour during monotonic and cyclic tensile testing of unidirectional SiC-fibre reinforced BMAS glass-ceramic composites
- Catholic Univ. Leuven, Heverlee (Belgium)
A model is proposed which gives a complete description of the stress-strain behaviour during monotonic and cyclic tensile testing of unidirectional SiC-fibre toughened BMAS glass-ceramic matrix composites using parameters describing the microstructure, the micromechanical behaviour, the damage development in matrix and fibre and the residual stress state as input. The model reproduces the main features of the stress-strain behaviour of the material and is versatile enough to take different damage development sequences and residual stress states into account. Furthermore, it offers the possibility to evaluate the impact of changes in microstructure and micromechanical behaviour on the macromechanical behaviour.
