FE Analysis of the Control Methods Used in Crimping of Joints with Polymer Composite Cores

Abstract

This paper presents results of the Finite Element analysis of crimped cylindrical joints with polymer composite cores. Initial data of the Finite Element analysis significantly affecting results of the simulation are design parameters and mechanical properties of the components. Initial interface clearance of the joint and hardening behaviour of the steel sleeve were found to have special importance. Material testing, and dimension analysis are conducted to find the parameters´ variation limits. Performed Finite Element parametric study allowed to compare quality of existing technological parameters in respect to residual strain energy of the core chosen as a measure of the load-bearing capacity. Analysis showed that extra mechanical work parameter is the most robust to variation of dimensions and mechanical properties.
