CRITERIA FOR MINIMISING TRANSIENT STRESS IN
2007-2-11 overcome transient stresses in the belt during starting and stopping. The high cost of the belt in most conveyor installations reflects these high f.o.s. values. A reduction in the f.o.s. can be achieved by reducing the transient stress in the belt caused by jerk or shock.

High transient stresses during starting and stopping a conveyor can cause tremendous harm to a conveyor system, resulting in belt and structure damage and belt splice and pulley failures. In some cases, it is difficult to measure these stresses and ...

[PDF] DETERMINING DYNAMIC BELT TENSIONS USING
Many problems which occur with belt conveyors can be attributed to system dynamics and the associated variations in belt tension. Material spillage, belt and splice failure, belt lift-off in vertical curves and poor tracking are a few examples of situations where knowledge of the dynamic tensions would be of benefit in eliminating a problem.

Changes in permeability caused by transient stresses ...
[98] Stimulation by transient stresses, much smaller than those that hydrofracture rock or cause shear failure, may be able to maintain permeability if the dominant permeability reduction mechanism is the clogging of flow paths by a dispersed phase such as colloidal particles. Identifying permeability reduction mechanisms is thus the starting ...

Changes in permeability caused by transient stresses ...
2012-6-1 Oscillations in stress, such as those created by earthquakes, can increase permeability and fluid mobility in geologic media. In natural systems, strain amplitudes as small as 10−6 can increase discharge in streams and springs, change the water level in wells, and enhance production from petroleum reservoirs. Enhanced permeability typically recovers to prestimulated values over a period
