摘要：

The extended finite element method (xFEM) was used to analyse fatigue crack growth in orthopaedic locking compression plates (LCP), made of Titanium alloy, Ti-6Al-4V, loaded in four-point bending. The optimal geometry was defined previously in respect to the remaining life of LCP used for patients with different body weights (BW - 60, 90 and 120 Kg). The plate with optimal geometry is analysed in more details here to assess the effect of BW and get better insight into fatigue crack growth path. (C) 2020 The Authors. Published by Elsevier B.V.
