The design of threaded connectors based on an elastic analysis appears overly conservative. This, in turn, will result in unnecessary material and manufacturing costs. To improve cost effectiveness, the design of connectors from the elastic-plastic viewpoint is warranted. This paper presents a simplified approach on the elastic-plastic finite element analysis of connectors. This approach would save tremendous computer costs which may be incurred in conducting a regular elastic-plastic analysis of threaded connectors.
