Finite element approach to modeling particulate bed fixtures

Prediction of workpiece deformation in a fixture system using the finite element method

“…Omitting fixture elements does not allow for the model to account for compliance in the fixture and neglects frictional contact effects between the fixture and workpiece. Other researchers [13][14][15][16] have utilized linear springs to approximate the stiffness of the fixture components. However, such an approach requires the stiffness to be measured or approximated, adding time and introducing potential error into the analysis.…”
