Comparative Behavior of Single-Bolted and Dual-Bolted Lap Joints
Publication: Journal of Aerospace Engineering
Volume 15, Issue 2
Abstract
Nonlinear finite-element models that predict the load-elongation behavior of single- and dual-bolted conical-head bolted lap joints are developed, and the load-elongation predictions are compared with experimental test data. The study is conducted for several panel thicknesses with a 4.8 mm size fastener and 2024-T3 clad aluminum alloy panels. The model load-elongation predictions are in excellent agreement with experimental test data. The results show that (1) dual-bolted lap joint test results underpredict the strength of single-bolted lap joints; and (2) numerical models may reliably predict the load-elongation behavior of mechanically fastened lap joints at a fraction of the cost and time of experimental testing.
