**5. Conclusions**

OOF2 based FE analysis is discussed for various ceramics composites. The thermal (thermal expansion coefficient, thermal conductivity) and mechanical (Young's modulus, residual stress) properties of the composites are predicated by OOF2 simulation and results are comparable with the analytical methods/models. A uniform temperature condition is applied to the composites and stress–strain distribution is analyzed. The maximum stress is found at the interface of the filler/matrix due to their mismatch of thermal expansion coefficient. The compressive and tensile stress distribution are observed in different composites with variation in their magnitude and localized at the interface. Similarly, a temperature gradient is also applied on the composites and found that the stress distribution depends on the orientation of the filler/grain. The thermal stress behavior is altered by fabricating composites via nano/micro-grain or making all grains parallel/perpendicular to the applied temperature field. The residual stresses are also varied according to the size, orientation and shape of the filler. Elastic stress also consists of a similar effect with filler size and orientation. A number of ceramics composites show analogous behavior at uniform/gradient temperature and displacement conditions. OOF2 mesh generation can be integrated with other software for failure analysis.
