Effect of Gap and Shims on the Strain and Stress State of the Composite-Aluminum Hybrid Bolted Structure

Figure 11

Comparison of the results of strain gauge measurement experiments, 3D-DIC measurement experiments, and finite element analysis when the assembly gap is 2.0 mm. (a) Strain gauges experimental results, (b) DIC experimental results, (c) FEM results, and (d) comparison of the results obtained by the three methods (C1: point 1 in composite; C2: point 2 in composite; A1: point 1 in aluminum; A2: point 2 in aluminum).
