摘要: A parametric investigation was conducted to determine the effects on load estimation method of varying: (1) thickness back-plates used in two-dimensional finite element models long bones, (2) number columns nodes outer medial and lateral sections diaphysis which back-plate multipoint constraints are applied (3) region bone optimization procedure density-based technique. The study is performed using proximal femora a chimpanzee, gorilla, lion grizzly bear. It shown that can be made more efficient accurate by restricting stimulus metaphysis/epiphysis. In addition, simple method, based variation diaphyseal cortical thickness, developed for assigning back-plate. also as does not have ...
