Table 4 Material parameters used for FKM approach

From: Mechanical strength assessment of a drilled hole in the contralateral cortex at the end of the open wedge for high tibial osteotomy

Material parameters Young’s modulus E [MPa] Yield strength Re [MPa] Elongation at break A [%]
Case H Case M Case L Case H Case M Case L Case H Case M Case L
Semi-ductile 17000 14000 15000 114 80 78 3.1% 3.7% 1.5%
Ductile 17000 14000 15000 114 80 78 6% 6% 6%
  1. The values of the elongation at break from the literature were used for the cortical bone considered as semi-ductile, while the value of 6% was chosen for the cortical bone considered as ductile
