Heterogeneous composite plates including inclined cracks were exposed to time dependent direct thermal stresses due to firing. The cracks were mixed mode cracks. The concrete heterogeneous composite plates were studied under the thermal stresses only and then studied under monotonic static loading after the pre-effect of the direct thermal stresses. The cracks were well observed during the effect of thermal stresses due to firing. The crack movements and failure resistance to thermal stresses were studied in addition to material strength effects. The heterogeneous composite plates were exposed to different degrees of temperature and different times of thermal effect. The results are important and useful for structural design, protection, repair and maintenance. The results can be applied for any heterogeneous composite. Concrete is a heterogeneous composite material involving the different solid materials bonded and joined together by cement.
