Method: Apply two kinds of residualtheory and influence of COX model to diagnosing the influence point of COX model, and compares residual analysis to influence analysis.
The expressions of load, displacement, stress and residual stress distribution for hole cold_extrusion process are established by using elastic_plastic theory.
