The elasto-plastic deformation of planetary roller screw pair under short-term high overload will reduce the transmission accuracy and increase the friction torque，which will affect the service life. Moreover，the radial load and pitch error have

Reducing overall vehicle weight is essential to reduce fuel consumption and pollutant emission and to improve noise, vibration, and harshness (NVH) performances. The substitution with lighter alloys can involve the grand majority of vehicle component

In this work, the effect of single overloads on plasticity induced crack closure is studied. An elastic-plastic finite element model was developed and the crack opening level was calculated from the contact forces along the crack flank. The effects o
