چکیده انگلیسی
The simulation results are further compared to results reported in the literature and to the analytical approach of Stoney (1909). For this purpose, a thorough review of the Stoney approach is done. We present an extended version with a plate stiffness for cubic anisotropic material and an additional formula to calculate the curvature from the thermal strain mismatch. It is shown that Stoney's approach to estimate the film stress from the curvature is inadequate for large deflections. A direct comparison to bending experiments with large thin coated wafers cannot be given since the deflection of these wafers is interfered from a predominant deflection from their dead load.
