Measured strain can be used to calculate the stress and the applied force. Strain guages are a special adaptation of this concept to help scientists and engineers to better understand the forces applied to an object.

This is a more detailed description of the relationship between stress and strain. In the elastic range of an object or component, there is also a straight line correlation between stress and strain. Once yield occurs the relationship between the two is much more difficult to define.

Although electronic programs or apps can be used to quickly and easily calculate stresses, stains, forces, and related data, this all can be done by pencil and paper hand calculations. It is vitally important for an engineer or practitioner to fully upstand the science of the process and perhaps even the hand calculation methods to guard against electronic tools providing false or inaccurate information.

-Acho útil nesse momento, analisar algumas hipóteses que podem ser assumidas em relação as propriedades mecânicas do material que se esta aplicando no modelo matemático. Essas hipóteses simplificam, e reduzem o tempo de processamento computacional, mas também podem limitar a aplicação dos cálculos. Como exemplo, hipótese de material isotrópico, para a mecânica da resistência dos materiais, define que as propriedades mecânicas são iguais nas três direções (xx,yy,zz), o mesmo para número de Poisson (deformação). Outro exemplo, hipótese de material elástico, modelo matemático trabalha na região elástica, abaixo da tensão de escoamento. Outra bastante aplicada é a de temperatura constante.

One very interesting dynamic application of stress and strain is to determine fatigue strength. This concept often involves relatively low stress and strain that is applied, removed, applied- over and over again. After said cyclical loading, must substances will be subject to abrupt failure with little warning. Engineers can use this to determine the number of cycles at a given force before fatigue failure. The force and the number of cycles can then be manipulated to achieve a desired lifespan before failure.

From an engineering perspective the disciplines that study stress and strain the most are mechanical, civil, and structural engineers. Civil and structural engineers tend to determine stress, strain, and forces in a static environment (stationary). Mechanical engineers do the same but also study the concepts in dynamic environments (moving).

Yield strength is an important piece of information for a subject. This is the loading point beyond which stress, strain, and force no longer have a linear relationship. This means the object will be permanently "bent" after exceeding yield strength. At some loading point after, with continued loading, the object will burst or fail strictly by overloading.
