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. The equation is typically presented as a linear curve of mean stress vs. A scatterplot of experimental data shown on an amplitude versus mean stress plot can often be approximated by a parabola known as the Gerber line, which can in turn be conservatively approximated by a straight line called the Goodman line. The general trend given by the Goodman relation is one of decreasing fatigue life with increasing mean stress for a given level of alternating stress. The relation can be plotted to determine the safe cyclic loading of a part; if the coordinate given by the mean stress and the alternating stress lies under the curve given by the relation, then the part will survive.

## Goodman relation

The paper reports on the results of a comparison involving mathematical models applied for fatigue life calculations where the mean load value is taken into account. Several models based on the critical plane approach and energy density parameter were tested and analyzed. A fatigue test results for three types of materials are presented in this paper. The specimens were subjected to bending, torsion and a combination of bending with torsion with mean value of the load.

Goodman relation is also called the Goodman diagram, and the Goodman-Hey chart, diagram or Hey Hey-Soderbergh-this equation is used to quantify the interaction of medium and alternating stresses on fatigue life of the material. The equation is usually represented as a linear curve medium voltage and the AC voltage which provides the maximum number of alternating stress cycles a material can resist before failing from fatigue. Scatterplot of the experimental data is shown in dependence of the amplitude of the average voltage plot can often be approximated by a parabola known as the Gerber line, which in turn can be conservative be approximated by a straight line called the Goodman line. ### Assessment of Validity of Selected Criteria of Fatigue Life Prediction

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. A scatterplot of experimental data shown on an amplitude versus mean stress plot can often be approximated by a parabola known as the Gerber line , which can in turn be conservatively approximated by a straight line called the Goodman line. The Gerber parabola is indication of the region just beneath the failure points during experiment. The Goodman line is much safer consideration than the Gerber parabola because it is completely inside the Gerber parabola and excludes some of area which is nearby to failure region.

Разумеется, на ее экране замигал значок, извещающий о возвращении Следопыта. Сьюзан положила руку на мышку и открыла сообщение, Это решит судьбу Хейла, - подумала.  - Хейл - это Северная Дакота.  - На экране появилось новое окошко.  - Хейл - это… Сьюзан замерла. Должно быть, это какая-то ошибка.

Ему в голову пришла другая мысль.  - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина. - Тогда вы наверняка ее видели. Это совсем молоденькая девушка.

В полном недоумении Сьюзан посмотрела в окно кабинета на видневшийся внизу ТРАНСТЕКСТ. Она точно знала, что на такой пароль уходит меньше десяти минут. - Должно ведь быть какое-то объяснение. - Оно есть, - кивнул Стратмор.  - Тебя оно не обрадует. - В ТРАНСТЕКСТЕ сбой. - ТРАНСТЕКСТ в полном порядке. Вопрос был лишь в том, насколько мощным. Ответ получили через двенадцать минут.

Мне кажется, коммандер приказал вам уйти. - Но монитор. Она показывает восемнадцать… - Коммандер Стратмор велел вам уйти. - Плевал я на Стратмора! - закричал Чатрукьян, и его слова громким эхом разнеслись по шифровалке.

Она чувствовала себя атеистом, лицом к лицу столкнувшимся с Господом Богом. - Если этот шифр станет общедоступным, - прошептала она, - криптография превратится в мертвую науку. Стратмор кивнул: - Это наименьшая из наших проблем.

Куда.

Мысли его были. Он ждал, когда зазвонит прямой телефон, но звонка все не. Кто-то постучал в дверь. - Войдите, - буркнул Нуматака.

Сьюзан удалось протиснуть в щель плечо. Теперь ей стало удобнее толкать. Створки давили на плечо с неимоверной силой.
