| shear stress |
the shearing force divided by the area. It is always a maximum at the outside of the flow channel. As it is force-related, it depends on the viscosity of the material, which in turn depends on the material and molding conditions. The maximum allowable stress level is usually taken as 1% of the tensile strength of the material. High shear stress is unimportant at gates, and in sprues and runners.

| shedding |
This is a "hairy" effect on the carpet surface caused by loose fibers or slack yarn twist, whereby the fibers slip out of the yarn bundle, either in service or wet cleaning. Shedding is not a defect, but rather a characteristic of all new carpet, especially cut-piles and wools. It is caused by short fibers within the pile that work loose during service.
