Overview
By modeling the tibia as a hollow cylindrical tube, we are to evaluate the resulting deformation, and
distributions of strains, stresses when under 4 different types of load with its lower end constrained.
Dimensions and mechanical properties are listed in the table. Four load cases are:
? Case a 450 N compressive load at the axial direction (~ 0.5 x 70 kg + 11 kg)
? Case b 500 N bending lateral load at y direction (causing bending)
? Case c 100 N?m torsion load (counterclockwise when viewing at negative x?direction)
? Case d Combined load from case a, b, and c
