“…Similar kinds of pixel selection and properties assignment are used by many researchers where two-phase materials or composites such as Ni-Al [37], Al-MgO [19], WC-Al 2 O 3 [20] and AlN-TiN [21] for various applications. Moreover, a varying ZnO composition from 4-10% is also studied by Manish et al [2] for NBT-6BT-ZnO composites.…”

“…In this direction, numerous composites, i.e., 0.94Na 1/2 Bi 1/2 TiO 3 -0. S. Patel et al [2,[19][20][21] predicted the mechanical and thermal properties of NBT-6BT-ZnO, Al-MgO, WC-Al 2 O 3 and AlN-TiN composites by the OOF2 method.

“…They show that an increase in the filler content increases the local stress concentration, which can be the start point of failure in the material. S. Patel et al [2,[19][20][21] also studied filler orientation, gradient and uniform temperature environment effect on the thermomechanical properties. Neeraj et al [4,10] obtained Y of Ni-Al 2 O 3 composite by OOF2 and compared it with the ultrasonic measurement with the possibility of crack initiation due to stress distribution.…”

This chapter discussed the object oriented finite element (OOF2)-based studies for ceramic composites. OOF2 is an effective method that uses an actual microstructure image of the material/composites for simulation. The effect of filler inclusions on the thermomechanical properties (coefficient of thermal expansion, thermal conductivity, Young’s modulus, stress and strain) is discussed. For this purpose, various ceramics composites (thermal barrier coating and ferroelectric based) are considered at homogeneous and heterogeneous temperature/stress conditions. The maximum stress is found at the interface of the filler/matrix due to their mismatch of thermal expansion coefficient. Further, residual and localized interface stress distributions are evaluated to analyze the composite’s failure behavior. The possible integration of OOF2 with other simulation techniques is also explored.

“…Sharma et al 17 examined thermal conductivity, thermal expansion coefficient, and modulus of elasticity for the interpenetrating phase composites of Ni/Al 2 O 3 using OOFEM. Patel et al 18 used OOF2 to study the structure–property relationships of AlN–TiN composites. It is found that compressive stresses are associated with the microstructure, and these stresses are largest at the interface of the AlN–TiN phases.…”

Multiscale modelling and simulations, based on molecular dynamics (MD) and object-oriented finite element method (OOFEM), are two important simulation tools to predict property enhancement of polymer nanocomposites for designing armor-type components in requisite applications. In this study, MD simulation software (Materials Studio) is used to develop 0.5%, 1%, 2%, 3%, and 4% (by weight) single-layer graphene (SLGR)-reinforced thermoplastic polyurethane (TPU) nanocomposites to find out their mechanical properties (mainly elastic moduli and Poisson’s ratio) using constant strain method. OOFEM simulation software (OOF2) is used for mechanical characterization of 0.5%, 3%, and 4% (by weight) SLGR-reinforced TPU nanocomposites from scanning electron microscopy–generated microstructures. Properties obtained from both the simulations are compared with experimental results to know the nanoreinforcement effect in atomic level as well as in microlevel in the nanocomposites. It is observed that the results based on OOF2 simulation are closer to the experimental results compared with the results obtained from MD simulation in this multiscale modelling and simulation study.

Multilayered TiN/AlN coatings find many technological applications where superhardness is suspected to be affected by AlN structures and template effect. Here, we demonstrate, by first-principles calculations on alternative adsorptions of Al and N atoms on Ti- and N-terminated TiN surfaces, that the preferred stacking sequences (i.e., having the largest adsorption energy) transform from fcc- to hcp- mode in first a few AlN layers. Using several analytic methods, we identify that for the T-terminated surface, the third added N layer is critical to inducing the structural transition of AlN, weakening the interaction between the second added Al and first added N atoms. The findings provide insight to the complicated template effects in TiN/AlN multilayered coatings, which are practically relevant for further improving property of multilayered coatings at the atomic scale
