A special clamping device was used to restrain the shrinkage
movement of the specimen during drying by keeping the dimensions of the specimen constant (Cheng et al.
The mean cross-flow direction and flow directional shrinkages
are as follows:
This residual stress cannot be computed directly by multiplying the free shrinkage
strain by the elastic modulus (ie Hooke's Law) since stress relaxation occurs.
Pack pressure has a significant influence on the amount of shrinkage
The ultimate impact of these decisions may depend on future developments, such as appellate review or possible IRS guidance providing a limited number of acceptable "safe-harbor" shrinkage
Cords in splice and adjacent non-splice regions have undergone similar length reductions due to shrinkage
(consistent with analyses of cords removed from cured tires).
Therefore, in the cases of packing time and packing pressure, the last two terms are more dominating than the first two, so that both the lateral and thickness shrinkages
are decreasing with those conditions as indicated in Fig.
These four steps were used to determine the temperature-related shrinkage
(that is, true thermal contraction plus moisture-related shrinkage
) behavior at high MC.
1) Area shrinkage
, which is an average of the directional shrinkage
values for a given area of the part;
If holding pressure is applied, shrinkage
is initially compensated by feeding more material into the mold cavity.
The corrected shrinkages
to 15 percent MC for the RF/V-dried squares were 1.
