This work describes the application of pseudodynamic (PsD) techniques to the deformation analysis of a passenger car seat submitted to the load effect from humanoid dummy action during a car crash. The certification of this type of automotive parts is usually based in applying to the car/part a defined plastic deformation resulting from a laboratorial loading state, the most similar to the one that occurs from an abrupt deceleration coming from an accident. The present work uses an alternative procedure to perform this test, where the action of the inertial forces resulting from the sudden decelerations during the crash, are updated along a sequence of time-steps in a hybrid numerical-experimental procedure, this constituting a PsD method.
