The analysis of elastic stress distribution in threaded tether connections

Abstract A technique is presented for predicting the load distribution and local stress distribution in threaded tether connections. The load distribution is derived by modelling the connection as a system of springs and beams. This distribution is then used in conjunction with the appropriate stress concentration factors derived by the finite element method to obtain the local stress distribution. A comparison is made between the theoretical predictions of local stress and published experimental results obtained from a photoelastic model.
