Keywords: bolted assembly, equivalent element, connector, traction.
The study of mechanical structures using a three-dimensional finite element, taking into account the problem of non-linearities (behaviour and contact) increases the time of the calculation and requires significant computer memory. Likewise, the optimization of the assembly (the number and position of the points) leads to an important number of calculations. The aim of the work, presented in this paper, is to develop a methodology which allows us to simplify a bolted assembly while keeping a realist physical behavior and to reduce the time of calculation of the numerical simulations. This paper focuses in the comparison of numerical and experimental results in the traction between two steel sheets with one fixity.
