Abstract
In this work, the mechanical behavior of the AZ31B-F magnesium alloy under cyclic loading is analyzed with the goal of contributing to the advancement of its use in the design of AZ31B-F components and structures. To achieve this goal, an experimental program was implemented to evaluate the cyclic response of the AZ31B-F under specific proportional loads with different stress amplitude ratios. Afterwards, regression methods were applied to extend the experimental data to a wide range of proportional loads. As a result, the AZ31B-F damage map, a material property that stablishes the damage scale between normal and shear stresses for finite life loading regimes, was obtained. In addition, a safety factor was developed for the AZ31B-F material when subjected to proportional loading. The achieved results have a direct application in mechanical design of components/structures made of AZ31B-F contributing to its reliability.

Nowadays, sustainability is a major concern for society
Societies are beginning to realize that change is needed, especially in the transportation industry, which today has a strong impact on the sustainability of planet Earth by contributing to the increase in greenhouse gas emissions [1,2,3]
This paper investigates the fatigue strength behavior of AZ31B-F under multiaxial fatigue testing conditions
Summary
Sustainability is a major concern for society. Over the years, industry in general has evolved without really thinking about the environmental impact of its strategies. Societies are beginning to realize that change is needed, especially in the transportation industry, which today has a strong impact on the sustainability of planet Earth by contributing to the increase in greenhouse gas emissions [1,2,3]. In this sense, alternative strategies have been developed to reduce gas emissions by reducing the weight of transportation structures. Alternative strategies have been developed to reduce gas emissions by reducing the weight of transportation structures In this context, the replacement of steels and aluminum alloys with magnesium alloys has been strongly considered. They are 33% lighter than aluminum alloys and 75% lighter than steels
