Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The use of a crash absorber in a vehicle is to absorb energy. The homologation procedure of vehicles makes use of many crash tests, which are extremely expensive for car manufacturers. This discussion aims to define a methodology for crash absorber design in automotive applications. The objective is to understand the effect of geometrical parameters starting from the theory of circular and square sections. A new approach for square and rectangular sections is then created. It has therefore been possible to define a preliminary concept characterized by the main geometrical parameters such as thickness, length of the two sides and fillet radius of the section and axial length. A finite element analysis was then performed to validate this. Furthermore, a DoE analysis (Design of Experiments) was performed, explaining the influence of complex geometrical parameters such as inner plate reinforcement and indentations in order to trigger the folding mechanism.
