Abstract


The interest in pushing the mechanical structures closer to their limits of usage makes necessary to combine the traditional design with the implementation of specific tests able to definitely confirm and guarantee their safety. Exploring the case of a large telescopic boom, the present study analyses the response to intense loads prevenient from static and dynamic conditions. The measure of deformations was oriented to validate several design assumptions, but also to investigate the presence of phenomena of local instability, not easily predictable within theoretical formulations.
