The shear modulus, G varies with the blend ratios. In the preblend system, the shear modulus decreases sharply with the addition of ACM up to the 50 50 blend ratio and then it remains constant with the further addition of ACM in the blend. In the case of preheated blend, the shear modulus decreases gradually with the addition of ACM. In both the preblend and preheated blends it is observed that the shear modulus at higher shear rate and lower shear rate gradually converge as the ACM content in the blend is increased. [Pg.618]

In terms of actual arithmetic operations, the direct inversion of large submatrices combined with an iterative method tends to increase the amount of arithmetic operations per mesh point. This is, of course, to be balanced by an increase in the rate of convergence. In the case of the iterative method SLOR, either in two or three space dimensions, it fortunately can be shown [6] by suitable normalization of equations, that no additional arithmetic operations are required for the successive line overrelaxation method (SLOR) over what is required by the successive point overrelaxation method, while an improvement in rate of convergence is always obtained.
