IMPACT FAILURE ASSESSMENT ON CRUSHER DISK BY RIGID AND ELASTO-PLASTIC BODY APPROXIMATIONS

Abstract: Rigid and elasto-plastic body simulations and analytical methods were carried out to identify and assess impact forces based on their contact durations and force magnitudes. Based on the estimations, most severe cases were simulated in ABAQUS to assess the possible damage on crusher disk component of crusher machines, designed and manufactured by MRT System Karlskrona. Further analyses were carried out to combine both impact force estimations and damage assessment. It was concluded that studied case of impact was not a likely scenario to cause the damage occurring under normal operation conditions in the studied type of crusher machines with the material properties considered in this work.
