In this paper, the initial part of a laboratory and numerical experimental campaign dedicated to historical masonry is described. One leaf panels with regular texture are built in order simulate material characterised by strong resisting elements weak mortar joints. Laboratory tests first components then behaviour compression panels, which applied both orthogonal parallel bed joints, highlight ...

Conclusions The present study has investigated the problem of the elastic response of a generic space vehicle with degraded joints. The steppedbeam formulation based on elementary beam theory is employed for extracting modal parameters of a normalized generic space vehicle. Next, the modal superposition principle is used with a low damping value for obtaining the elastic response of the vehicle...

This paper presents a method to optimize the energy efficiency of walking bipedal robots by more than 50 % in a speed range from 0.3 to 2.3m/s using elastic couplings – mechanical springs with movement speed independent parameters. The considered robot consists of a trunk, two stiff legs and two actuators in the hip joints. It is modeled as underactuated system to make use of its natural dynami...
