The results show that bolts can offer both stress constraint and displacementconstraint to rock mass, and provide a basis for support design and stability...

This paper developed a three dimension finite element model to analyze stress distribution on residual limb of crus under lumped loads with different displacementconstraint conditions.
The purpose of topology optimization is to find a distribution of the structure, so that it can meet the volume, displacementconstraint conditions et al, and attain some optimal performances.
