This work aims to analyze the mechanical behavior of a pre-cracked cup of a total hip prosthesis in severe circumstances by using numerical simulation. ABAQUS-6.8 as a numerical simulation software was used. It is assumed that the prosthesis was implanted in an adult subject under an excessive load. The obtained results were satisfied.enOther
