The straightening process is the main cause of residual stresses in the manufacture of rails. It is a non-trivial process with cyclic plastic loads, solid–solid contact and complex geometry, which computational simulation is often complex and time-

Over the years the electricity generation based on alternative energy systems applied to remote regions has been increased in Brazil, mainly due to the lack of conventional electric grid structure, specially in places as the Amazon. In this scenario,

Most small wind turbines do not have pitch adjustment of the blades. This makes starting at low wind speed a serious challenge which is magnified by the drivetrain resistance caused by bearing friction, generator cogging torque and so on. Typically t
