The copper tubes have been deformed because of the anisotropy in the compressive stresses resulting from the higher thermal contraction coefficient of aluminum.
s) has the expression corresponding to Maxwell mechanical model, specifically for plastics, G is the transversal elasticity modulus, K is the compressibility modulus, v is the transversal Poisson contraction coefficient and [eta] is the constant corresponding to Newtonian component of the Maxwell model.
The LE, linear expansion coefficient (LEC), LC, and linear contraction coefficient (LCC) were calculated as follows:
The contraction coefficient [phi] is defined as the ratio of area of contracted jet to the area of tangential port.
p] Velocity in Tangential Port [PHI] Ratio of Discharge Coefficient for Viscous and Ideal Liquid [alpha] Cone Angle [lambda] Friction Coefficient v Kinematic Viscosity [rho] Density [phi] Contraction Coefficient
c] = contraction coefficient, the ratio of the jet area at the vena contract a downstream of the bore to the area of the bore itself (dimensionless)
c] = change in contraction coefficient due to plate deflection (dimensionless)
Their published formula is different in two respects, however: (1) their approximation for the deflection angle of the bent plate assumes elastic, not plastic, plate deformation, and (2) a different correlation is used for the contraction coefficient, [C.
and [phi]' for the deflected plate is determined using the [beta] ratio before deflection, but the contraction coefficient [C.
Finally, the contraction coefficient correlation, taken from von Mises (1917), is given by Equation 7, with values of Mi interpolated from Table 2.
making a very precise scale model, which should take in consideration in its geometrical dimensions the contraction coefficient of the cast part alloy.
