Aspects énergétiques des phénomènes mécaniques

Conservation de l'énergie mécanique. • Lorsque le système n'est soumis qu'à des forces conservatives, l'énergie mécanique est constante (se conserve), c'est-à-dire que la variation d'énergie mécanique est nulle. On a alors : Δ Em = 0. • Exemple : un pendule de masse m est mis en mouvement.

    Developed Trigger Mechanisms to Improve Crush …

    Among all crushing modes, axial progressive crushing has higher energy absorption due to the involvement of higher plastic deformations. It was observed that initial peak force is much higher than the subsequent ones and this leads to lower CFE. So, to increase CFE, it is required to introduce small imperfections called trigger mechanism [16].
