Load and Stress Calculating

When you are testing load and stress, you are essentially pushing the object you are testing to its limits. Whether you are testing items for engineering such as belleville disc springs or testing software for computers such as servers, load and stress calculating generally serves the same purpose: it is a measure of how much load and stress your subject can take before it fails or caves. As noted in some of our other articles, there are many factors that can increase or decrease the load that an object can take. For instance with belleville disc springs, stacking them in parallel will greatly increase the load they can carry. These calculations are something that is very important in machinery, if a bolt or joint cannot take the load or stress of internal and external factors, it is for certain that it will fail. It is always recommended that prior to purchasing new engineering supplies that the proper calculations for the amount of load and stress are made. Other important procedures in the industrial engineering world are the practice of deep hole drilling and live loading.

The Practice of Live Loading

In the industrial world, there are many different procedures and systems that are used. Essentially, live loading is the addition or application of a spring load to a packed valve. What this does is to effectively control the amount of stress in a packing set by placing a belleville disc spring between the gland follower and its fastening studs. This is all controlled by the various factors that affect load and deflection in a disc spring such as thickness, material, diameter, and other variables that you can read in some of our other articles. The load and stress calculating of the disc springs will give you the amount of packing stress that you can effectively control. Even when the packing volume is lost by external conditions, the follower always pushes against the packing. The method this system employs allows packed valves to remain virtually free of leaks.
