What is the voltage concentration?
The voltage concentration is a phenomenon that can be caused by an opening, a sharp bend or a defect in the object when force is applied. The reason is that the discrepancies in the structure of the building will tend to result in building stress in certain areas. These places are usually referred to as voltage concentrations because they represent areas where stress forces increase. The object, which is relatively uniform in the structure, will tend to be much more resistant than a similar object that has one or more concentration of voltage. This is due to the fact that the increased pressure found in the voltage concentration usually leaves the object much more vulnerable to damage when cracking, cracking or breaking in a different way.
When the structure of the object is relatively even, the stress will tend to be evenly distributed throughout the fabric. One way to visualize is a flat plate with evenly distributed force lines running along the surface. If the hole is drilled in it, whatThe voltage -applied tension applied to the board will be concentrated on both sides of the hole. The reason is that the power lines cannot pass the material that has been removed when the opening was drilled. The Chinese forces must pass through the hole, resulting in a concentrated voltage area, causing the plate to break at this point if excessive force is applied.
virtually any object that lacks a completely uniform structure will contain a certain type of voltage concentration. If the substance that is made of the object contains any contaminants or defects, no matter how small, it will tend to lead to concentration of power lines. This makes it particularly important to remove any contaminants in the construction of objects that will be exposed to high stress. Small cracks also result in voltage concentration, which can lead to much larger fractures over time.
geometricThe object of the object can also lead to voltage concentration. Some common examples include hollow and right beam angles and shafts with peripheral grooves or shoulder fillets. Each of these shapes has a different formula of voltage concentration, which may, in certain circumstances, lead to an object failure or component. Due to the lack of any supporting material in the center, the hollow square beam will have failed a square if it is twisted. Other items such as shafts that have grooves or fillets may fail under twisting, bending or axial forces.
