flow stress is yield stress of material during plastic deformation
Any material can flow under stress.
In rock masses, the stress distribution can significantly influence water flow in fractures. When rock stress increases, it can cause fractures to close or reduce their aperture, impeding water movement. Conversely, if stress decreases, fractures may open, enhancing permeability and allowing for greater water flow. Additionally, the interaction between stress and the orientation of fractures can further complicate flow patterns within the rock mass.
The critical stress at which a material will start to flow is called the yield stress. It represents the point at which the material transitions from elastic deformation to plastic deformation, causing it to permanently deform under applied stress. Yield stress is an important mechanical property that determines the material's ability to withstand deformation.
Shear flow is the flow induced by a force gradient (for a fluid). For solids, it is the gradient of shear stress forces throughout the body.
I would say oh-ver-FLOW-ing, with a minor stress, perhaps, on 'oh'.

Long term stress can have a detrimental affect on physical and mental health.
Increased blood flow can aid in healing. Massage can increase blood flow. As long as the massage does no further damage to the stress factor, yes it could aid the healing process.
A viscoplastic fluid is a type of fluid that exhibits both viscous and plastic behavior under stress. It can flow like a viscous fluid under low stress conditions but behaves like a solid under high stress, showing a yield stress below which it does not flow. Examples include toothpaste and clay suspensions.
Wind stress curl is a measure of the twisting or rotational effect of wind stress on the surface of the ocean. It represents the change in the horizontal wind stress field with respect to direction, indicating the tendency for water to converge or diverge in the surface layer. Positive wind stress curl leads to convergent flow and downwelling, while negative wind stress curl leads to divergent flow and upwelling.
Newtonian fluids have a constant viscosity regardless of the applied stress, while non-Newtonian fluids have a viscosity that changes with stress. This affects their flow properties as Newtonian fluids flow consistently, following Newton's law of viscosity, while non-Newtonian fluids can exhibit different flow behaviors such as shear-thinning or shear-thickening, depending on the stress applied.
A nuclear stress test is typically used to evaluate the flow of blood through the heart during activity using a radionuclide tracer. This test helps to identify any blockages or abnormalities in the blood flow to the heart muscle.
