• The actual stress in an elbow is about twice the calculated value. This is not unusual as it is a characteristic of the B31 flexibility analysis rules, since the fatigue limit is based on the nominal bending stress in butt-welded pipe.
Stress is the amount of force per area on an object. The maximum stress that an object is expected to support is called the allowable stress. For example, the floors in a library might have an allowable stress of 150 pounds per square foot.

Sep 09, 2015· S = stress value for material from Table A-1 Y = coefficient from Table 304.1.1, valid for t < D/6 and for materials shown. The value of Y may be interpolated for intermediate temperatures.
Quick Engineering stress is the applied load divided by the original cross-sectional area of a material. Also known as nominal stress. True stress is the applied load divided by the actual cross-sectional area (the changing area with respect to time) of the specimen at that load Engineering strain is the amount that a material deforms per unit length in a …
