Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material. [1]
Smith diagram or Smith diagramme may refer to: Smith chart , a diagram by American electrical engineer Phillip Hagar Smith, used in electrical engineering Smith fatigue strength diagram [ de ] , a diagram by British mechanical engineer James Henry Smith [ de ] , used in mechanical engineering
Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient treating the Smith chart as a polar diagram and then reading its value directly using the characteristic Smith chart scaling. This technique is a graphical alternative to substituting the values ...
Paris' law (also known as the Paris–Erdogan equation) is a crack growth equation that gives the rate of growth of a fatigue crack. The stress intensity factor K {\displaystyle K} characterises the load around a crack tip and the rate of crack growth is experimentally shown to be a function of the range of stress intensity Δ K {\displaystyle ...
In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
They include unexplained weight loss, headache, pain, fatigue, loss of appetite, night sweats, and malaise. [21] A group of three particular nonspecific symptoms – fever, night sweats, and weight loss – over a period of six months are termed B symptoms associated with lymphoma and indicate a poor prognosis. [22] Other sub-types of symptoms ...
"Constitutional carry" has become the favored term of supporters for permitless carry in discussions of concealed carry laws, possibly because it's catchier and adds an emotional, patriotic impact.
The purposive approach (sometimes referred to as purposivism, [1] purposive construction, [2] purposive interpretation, [3] or the modern principle in construction) [4] is an approach to statutory and constitutional interpretation under which common law courts interpret an enactment (a statute, part of a statute, or a clause of a constitution) within the context of the law's purpose.
