Today, a major obstacle to developing locomotion mechanisms that are as safe and energy efficient living organisms has been overcome with the development of actuators adjustable stiffness. This work presents an innovative clutch mechanism whose stiffness can be adjusted based on combined bending torsion prismatic beams. In this way, any rotary actuator help mechanism. The consists elastic beams...

In this paper the effect of different hardening models in simulating the U-bending process for AA5754-O and DP-Steel, taking a benchmark of NUMISHEET 93 2-D draw bending, has been discussed. The hardening models considered in simulations are: isotropic hardening, pure (linear) kinematic hardening and combined (nonlinear kinematic) hardening. The influence of hardening models on predicting sprin...
