Within this thesis, two ergonomics (i.e. seating comfort and long-distance driving fatigue problems) and two structural bio-mechanics (i.e. femur-fracture fixation and radius-fracture fixation) problems are investigated using musculo-skeletal multi-body dynamics and finite element computational analyses.
Within the seating comfort problem analyzed, a complete-body finite element model is constructed and used to assess the effect of seat geometry and seating posture on the feel of comfort experienced by a seated human.
Within the long-distance driving fatigue problem, musculo-skeletal analysis is employed to assess the extent of fatigue experienced by a driver through the evaluation of level of activity of his/her various muscles.
Within the femur-fracture fixation problem, physiologically realistic loading conditions associated with active daily activities (i.e. cycling) are employed within a finite-element frame work to assess fracture fixation performance and durability of the implant.
Within the radius-fracture fixation problem, the analysis developed within the femur-fracture fixation problem is further related to indicate the effects of other types of loadings (associated with additional daily activities) and improved biological and structural material model are employed.
For all cases studied in the present work, relevant experimental data are used to validate the computational procedure employed.
