Predictive capabilities of Vibration-Correlation Technique applied to axially compressed CFRP truncated cones

Sensitivity analysis for buckling characterisation using the vibration correlation technique

“…The numerical analyses were conducted using the ABAQUS finite element software and had the measured dimensions, shapes and thicknesses imperfections of the cylinders implemented using the approach described and validated in [42], thickness and shape imperfections reported in detail in [36]. In this approach, the material properties of the elements are also altered to account for the measured thicknesses.…”

“…The influence of internal pressure was also studied in the work of Franzoni et al [20,23], who showed that VCT is also applicable to stiffened pressurised cylindrical shells. Regarding truncated conical shells, Gliszczyński et al [36] investigated the predictive capabilities of VCT for types of structures, using the FE models of two composite cones of nominally identical geometry, but with different ply topology. An extensive parametric study, considering different bottom radii, semivertex angles, length, plus initial thickness and shape imperfections, was also performed.…”
