چکیده انگلیسی
In this work, a new temperature dependent fracture strength model for the laminated ZrB2 based composites is developed by employing a temperature dependent fracture surface energy model and the classical fracture theories. The model unifies the effects of temperature, temperature dependent residual stresses owing to added reinforced particles and laminated structures, microstructures and laminated structures on the strength of laminated ZrB2 based composites into a single theory. Using the model, the effects of microstructures and laminated structure parameters on the strength of composites and their evolutions with temperature are studied in detail. The micro and laminated structure parameter optimizations for improvement of the material strength are discussed. The model is verified at different temperatures by comparison with experimental data of different laminated ZrB2 based composites. Excellent agreement is obtained between the model prediction and the experimental data.
