摘要: The elastic behavior of a cross-ply fiber glass-reinforced epoxy laminate loaded in tension through pin fitted with clearance and interference is examined. A nonlinear contact analysis using the Finite Element Method an experimental study by Speckle Interferometry are performed, showing fairly good correlation. An interesting comparison performed between FEM results Hertzian theory. Major conclusions are: (I) causes high compressive stress bearing area, does not influence peak tensile stress; (2) has beneficial effects on joint, as (a) it lowers circumferential stress, (b) decreases change due to application load. This last conclusion suggests that can improve fatigue life joint.
