Anisotropy transverse shrinkage

Figure 8 shows the degree of shrinkage against tensile load. The direction of stretching and transverse direction shows the expected anisotropy. As the load increases, the shrinking strain shows more hysteresis. 

Mould Shrinkage A measurement of the contraction of the moulded material in comparison with the original mould dimensions. Two values may be quoted where material flow induces anisotropy in material microstructure, e.g. preferential alignment of reinforcing phases. Example 2.0/3.0 indicates 2.0 % shrinkage in direction of material flow, with 3.0% shrinkage transverse to mould flow direction.
